Here's my disclosure:

1) serial number 4529, stamped only on the left side of the barrel
2) early one-piece magazine housing, no seam at the top, blued black
3) early bolt with a central slot, blued black, stamped and folded black extractor
4) early ejector, centered, with a thin blade on a post
5) early recoil assembly with a two-part telescoping piece, blued
6) early trunion, bare metal
7) early solid receiver without a hole under trunion
8 ) early grip assembly with "Made in Japan" stamped underneath
9) early muzzle nut, machined and pressed on by force
10) trunion screws: ?? no idea if mine are large or small
11) early foregrip: very dark brown

PS: man, I so dislike putting the receiver back together, it just never wants to snap correctly in right places...

Hello fellow modelgun aficionados!

I have just taken delivery of my 3rd MP40 modelgun, this one a MGC 68! Very Happy

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! Wink

(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:

"The telescopic section of the recoil tube, sticks to itself when you close it, turn it slightly and it releases."

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.
