I have just taken delivery of my 3rd MP40 modelgun, this one a MGC 68!
Here is the data -
1. Serial 4779 on left rear of barrel 2. Mag hsg - Early 1-pc no seam rusty brown 3. Bolt type - type 2??? offset elector cut, no angle mill, large cut on side 4. Ejector - Mid/late offset post 5. Recoil assy - early/mid 2-pc tube pressed into bolt body 6. Trunnion - mid/late chromed Zinc 7. Receiver - doesn't seem to have any 'cut' behind mag hsg 8. Grip - Early "Made In Japan" 9. Muzzle nut - Early blued press-on 10. Trunnion screws - Small? - heads measure ~.214" OD 11. Forearm - appears black
Other observations -
- Grips are brown, no spacer between grip screw & nut (large hole) - MGC 68 magazine - Bbl plug, no detonator pin - Resting bar has big chip out of front; does not stay on - Barrel has internal blocking 'rib' - Barrel nut seems to have too steep a chamfer
This replica is well used, rusty in most areas, although bolt face is unmarked...
If anyone has any source for an intact resting bar, I would be interested!
(Otherwise I will attempt to make one out of Delrin).

1. Serial Number #13774
2. magazine housing. Early: No seam, one piece-stamped steel assy. Dark blue color.
3. The bolt type: Type two. late, offset ejector slot. Not milled - it will feed dummy rounds.
4. Ejector: Mid/Late: offset mounted reinforced post zinc alloy.
5. Recoil assembly: Early/mid production: small diameter spring in a blued, two piece, drawn steel, telescoping tube.
6. barrel trunion: Mid/late: blued or chromed zinc alloy
7. Receivers: Early "solid" tube without cut below the barrel trunion. Single hole and slot for lower assembly. purple color/tint.
8. Grip assy: Late: "Japan" on trigger guard.
9. Muzzle nut: Early: Machined, non-threaded pressed on, usually with a blued steel finish
10. Trunnion screws: Early: Black oxide finished allen bolt with a small head/shank.
11. Forearm Mid/Late: Black
Other observations: This may be a later muzzle nut - but, it has remained black.
Blowing down the barrel - air is venting. There is a hole drilled beneath the barrel locking nut - some air escapes here. There is a hole drilled in the top of the barrel locking nut too - a flat headed brass "rivet" has been fitted here, which prevents the barrel locking nut from being unscrewed, so I cannot remove the barrel.
The telescopic section of the recoil tube, sticks to itself when you close it, turn it slightly and it releases. This causes the bolt to stay to the rear, sometimes, working the cocking handle a couple of times releases it.
The chamber:

This flow chart is invaluable for minor fixes.

Ha ha - we went to the same school of engineering! Always good to hear from an expert.
The ends of the MP40's first-section of piston actually overlap the second just slightly when it closes fully, it could probably be fixed with a file, but I'm not going to touch it.
Here it is locked closed - a slight twist and it opens again.
As I had the bolt out, I photographed the bolt face, too. Uncut but chipped. I don't shoot caps, so not an issue -
Side-note: Stopped using WD40 on any of my guns: with semi or full auto blank firers, you can have issues with over-pressure, if you have a surplus of WD40 in the barrel - especially if you have some assistant who sprays a dob in just before a shoot, thinking he's helping things. I do not let WD40 come anywhere near my guns - the Byf42 MP40 in the picture above cost ten times what my first car did.
On the WW2 guns we/I use dedicated gun-oil and/or a light-layer of gun-grease - On the AR's and modern AW's I've been using a thin film of frog-lube CLP. On the Flinters and percussion just a thin layer/film of 3 in 1 household oil, after a very hot-slighty-soapy bath.

Subject: Didn't know what I had until now Tue Dec 22, 2020 7:24 pm
I was unfamiliar with model guns until this weekend. When I was ~10 years old I traded a bayonet for this MGC68 without knowing what it was, we used it for playing war and home movies. My grandfather who was infantry in the US Army during WWII in Germany looked at it long ago. He said it looked and felt right but was puzzled by the barrel not being rifled or made of steel. At the time we'd never heard of high end replicas or model guns. Eventually it got put in a closet for 35 years until rediscovered. With the internet it's been much easier to find out it's history.
Mine is one of the early non-firing versions with an uncut bolt. Ideally I'd like to restore it and convert it to fire MGC P220 9mm cartridges by getting a machine shop to fabricate the det pin using specs on this forum. Big question is if I'm able to get cartridges and caps shipped to the United States. I did see that KSC 9mm carts would be another option though someone had written their extractor had a problem with that cartridge.
Additionally mine is missing a few parts, ie. the hood for the front sight, the barrel thread protector that goes on the muzzle, the barrel resting bar and the charging handle for the bolt was broken off at some point. I should be able to fabricate one from steel and drill a hole into the zinc bolt and then JB Weld it in place, if that seems to be the best option.
Does anyone have recommendations on getting the missing or broken parts? I sent an email to plugfirecapguns in the UK and waiting to hear back.
Below is my disclosure:
1. Serial # NO.2732 left side by barrel nut (not muzzle nut)
2. Magazine housing: no seam, blued w/ light rust.
3. Bolt type: type one blued.
4. center mounted blade
5. 2 piece telescoping tube type
6. plain, no holes drilled by the factory
7. solid
8. "Made in Japan"
9. Missing, as well missing the sight hood
10. Early small.
11. Missing

Looks pretty beat up but no problem with a little TLC and research on this web sight you can have that old boy up and running in in time. Looks like you may also need a muzzel nut, no worries I'am sure we can find you the parts you need if you choose to embake on a rebuild. Good luck and let me know if I can help.

Hello dcraven67,
It's good to see you here, welcome!
Thank you very much for adding your MP40's details to the register.
Looking at the photo of your bolt, it looks to be unground and uncut. The boltface is complete and should hold a suitable cartridge. It's unfortunate that the charging handle has broken off. Another Japanese manufacturer, Marushin, made replica MP40s. A good modification when making replacement steel bolts was to fit Marushin's working push/pull safety charging handle to replace the solid cast MGC type. Finding Marushin spares is very difficult now.
A new extractor could be made to accept KSC 9mm cartridges. The Detonator Pin may well need it's length adjusting to accept KSC cartridges though.
Used parts appear on Japan's Yahoo auction site occasionally. Ebay.com has a seller based in Hawaii selling replacement parts too if exporting from PlugFireCapGuns.UK is a problem.
If you find parts here and cannot bid/buy directly, I'm sure one of our Japanese members can help you out.
Keep in touch, we're here to help

Hello collectors, following is my MP40 Info.
First, I aquired my MP40 in the late 80's. My cousins father in-law had this gun on display in his vintage warbird Fieseler Storch Fi-156 observation aircraft. He would regularly fly this plane and show it at airshows. It was in full German markings and this MP40 hung in the rear observer/gunner area. Well, he had a fuel pump failure near his home and the plane crashed and was a total loss. My cousins father in-law was very lucky and got away with only minor injuries. I was able to purchase the MP40 from him. He kept the MG-15 that was in the rear along with the other German soldier and pilot gear. (Darn!) Anyway, I've had it forever and just happened to find this site while trying to find out how in the heck to get Caps in the USA so I can shoot the thing. Maybe someone can fill in the new guy why they aren't available here. There must be a story to that.
Mine is an MCG MP40 (mgc68). Info: 1. No. 5347 2. Early - No Seam 3. Type 2 Bolt 4. Mid/Late - Offset Ejector 5. Early/Mid version – Telescoping Tubes 6. Early – Zinc Alloy (Chrome?) 7. Early – Solid Tube 8. Early – 'Made in Japan' on Trigger Guard 9. Early – Machined Blued Steel 10. Early – Black Small Head 11. Early - Dark Brown
I was recently fortunate enough to shoot a real MP40 at a rental range. Very controllable fire, and great fun. An old gentlemen next to us had two real Sturmgewehr 44's (StG44's). WOW.
Best Regards, Mike (Boss2X)
