Holy smoke
You can tell all that from just looking at the pics
Cerwyn, you can get a PhD on the subject
I was kind of disappointed that there's no serial number on the gun
So, as you rightly pointed out, it is a mid to late production '40 - I & my brother have yet to gather enough courage to strip our '40s to check the the bolts & receivers
I will probably end up sending mine to Kickback to have mine converted to a blanker when my MVT membership comes through in June. So wait for Kickback to update you on my '40.
I will do my best to get a pic of the barrel plug of my brother's '40, but without knowing how to strip it , it's gonna be difficult
Thanks for identifying the '40, you've been a fountain of information
BTW, would you know if this model gun '40 could be converted to a blanker , or should it be kept "as is" purely for collectable value

P.S. My brother's '40 only cost him US$500 (including shipping & import duties), mine was a fraction more but his is just awesome - it's almost mint
