Did the Finns use stock discs post war?
Yes they did but again the use was not common. War era discs will be brass in look and color while the post war discs look like aluminum. In many cases these post war discs are artillery units the most common being 2.PSTO KAR PR. which is the 2nd Karelian Artillery Brigade these discs as far as I know being seen only on M39’s. I have never seen a wartime M39 stock disc as it seems the Finns banned the use of these discs before M39 production got underway as a security measure. What is not known is why the practice was once again undertaken post war.
