Picture request: AK underfolder lock mechanisms

[NeoWeird]

Hope no one thinks this is in the wrong location; I put it here because I need a reference to make a part for a project gun of mine.

I have several underfolder AK parts kits but all of them lock in the horizontal position; I have none that lock in the ~30 degree downward slant position. What I'm looking for is a picture that shows the difference between the two. Is it the same locking trunnion and the stocks are different or are the stocks the same with different spaced locking holes or are both trunnion and stock unique to each type?

If you know the difference and can explain it but don't have pictures that could help too.

Thanks.

The difference is in the stocks. The locking system on both meets the receiver parallel to the top rail. The holes in the stocks are offset on the 30 degree stocks, and in line with the stock on the straight ones.
Picture is of a Romy stock (30 degree on the bottom), and Yugo stock (straight on the top).


Thanks Toes.
New phone, and I haven't quite figured out the image thing yet. :P

Thank you very much. Now let me ask you something; I understand how it locks open in the offset position, but how then does it lock parallel when locked closed? Maybe I'm missing something, but it would seem to me, at least logically, that it would want to lock the ~30 degrees past center line like it did when opened and would want to fold up past the barrel.

So if the rear trunnions are the same, and there are only two holes, why does it lock parallel to the bore when closed but locks 30 degrees below parallel when locked open?

I happened to have my romy underfolder sitting right here and when I looked at it I saw that the piece that goes into the holes is notched. Only part of it goes into the hole when the stock is folded and the whole thing goes in when it is open.



You can see the notch in the pic. That is the only pice that goes into the stock when it is closed
