Hello all,
Quick question is there a way to tell which country an underfolder is from based on how it is built or the rivet pattern? I recently received some underfolder kits that are supposed to be polish and the one has a polish underfolder (it looks like the underfolder in the kit I got from global trades). The other is a mystery to me. The construction of the underfolder is completely different as is the rivet pattern. Plus the polish underfolder trunnion seems to be almost flat on the back where the other one seems to be angled slightly. Any help in identifying this would be great. I will try to get pics posted in a little bit.
Thanks!

Maybe your mystery Polish, is a diamond in the rough and might be worth a large sum of money.....especially after hearing about the demill jobs on these. Just trying to think positive things about these kits!!!

Mike--the Rommie underfolder is flat on the back. But don't you have one of those?

Winn,
I have a polish underfolder from global (that I bought through sportsmansguide) and I have the two polish underfolder kits I recently got from centerfire systems. The first all numbers matching kit from center fire has a underfolder like the globaltrades kit. The other is all different numbers and a hodge podge so to speak and the underfolder is a different rivet pattern and everything.

Here are some pics:
closeup of underfolder in kit #2 this almost reminds me of a chinese underfolder - but then again the receiver doesn't look thick enough to be chinese. Any ideas?



rear underfolder trunnion from kit #1


notice the straight backside of the trunnion area where the one in kit #2 was curved slightly.


some differences in the stocks. Looking at the stocks - I don't think they both came from poland, unless one is a newer style - does anyone know?

Sniper,

Your first kit looks like both of my rear trunnions. The second is quite a bit different. It definitely has a slant to it. Do you have any overall shots (closeups) of the nice kit...I'd like to see the finish and condition of it.

"underfolder trunnion seems to be almost flat on the back" <------- this is the correct underfolder unit from Poland as it is built on every AKM (notice I said AKM) Doesn't matter which country it is built from, these underfolder unit are made from casting and all AKM underfolder are straight flat on the back when fully extended. Reminder--->AKM stands for AK-47 Modernized.

"the other one seems to be angled slightly"<---- congradulations! this underfolder unit is no mystery at all...you got lucky and got yourself a truely early version of the AK-47 (notice I didn't say AKM). This underfolder unit is made from milling the entire unit into its final form. These under folder type are not suppose to be built on stamp receiver but instead was originally built on milled receiver. According to your picture someone got lazy and had built this on a stamped receiver. Go check out Arsenal Inc website ---> http://www.arsenalinc.com/images/sasm7classic.jpg and look at their SAS M-7 Classic and see the angled-downward of the rifle and see that it is built on a milled receiver. So to answer your question...this unit was built from Bulgaria.

If you looked closely...the casted underfolder has rivets toward the end of the buttplate with dimples versus the milled underfolder which had no rivets at all and no dimples.

If I am wrong someone correct me and I am willing to learn. P.S. I didn't based my info soley on Arsenal website but have extensively looked at books.

I had also found out that the underfolder that is angled in the back with the different rivet pattern matches the angle and rivet pattern of a chinese 56-1 underfolder.
