What is the differance between the cupped buttplate and a flat one. I have looked at both and am not sure which is which.

See part 39 and 39b.

39B is cupped - the buttstock is relieved so it can actually fit inside the cupped buttstock.  If you have a Yugo M48 you can see they have a cupped buttplate.  If you remove the cupped buttplate you'll see the wood stick into it a good inch and a half or so.

39 is flat.  Buttstock and buttplate simply abut.

the cupped came about to help the then new plywood (laminanted) stocks from de-laminating in field conditions.  it totally covered the rear portion of the buttstock.

flat was early war issue, cupped was latter war issue.  There were 2 versions to the cupped, mid war had no hole drilled in the bottom for bolt disassembly, end of the war did.

Does someone have a picture of the cupped buttplate with the hole for bolt disassembly?  I thought that's what the hole in the stock was for.

I have a 1944 built "ar" code with the cupped plate.

I guess the easy way to remember the difference between the flat/"sniper" and the cupped plate is that the cupped looks a bit more "desperate" for the times the Germans were facing mid-late war.

Last ditch rifles were built without the disassembly disk in the stock and they drilled roughly a 1/4" hole in the bottom of the cupped buttplate.  Late war production can be ID'd as stamped floorplate, stamped upper and lower barrel bands.  The stock laminations are rougher and poorly finished. Alot of them didn't have a bayonet lug or a hole for the cleaning rod. A 44 would still most likely have a standard cupped with the disk in the stock.
