The ones meant for the wire hangars appear mostly on m/91's and 91/30's with a smattering on some m/27's that have one of the varaint stocks which means it could have been a 91 rear section to start. But mostly the plates with the holes in it was used on 91's.Were the small, oval-shaped sling slot escutcheon plates used by the Finns ever used on any models other than the M91 and M91/30 to cover the sling slot holes in the stock? Thanks.
