Thread: Brno 22 hornet

Got my hand on one in fairly good nick. It's got a stamp with 58 next to it( I take it it's yr of manufacture). Then same stamp on chamber with zkw465 and then a tiny scroll which I can't decipher. On top of barrel 22 hornet. On other side of chamber the number 22341. Then made in Czechoslovakia at the back
Any words of wisdom welcome. A very quick sight in today and I think about 3/4 inch.l
