What does the stamping that has a square with the letters SA mean? I have a fin 91 that has it but also a german starter tab with it.
Click on my thumbnail at top of this post to see stamping. The other side has the eagle and hooked cross. Also has w?ac42 under that. The Finnish must take a piece and stamp it as their own.If the MG42 starter tab has a boxed SA (Suomi Armija, I think is the Finnish translation), then yes, it was used in the Finnish Army.
