The numbers are half an inch in size and by the butt plate on the left side. They look deep and the wood fibers look crushed/cut. Not sure they will steam out. I heard the Russians stamped these, however there is no shellac on it? We took it to the range today and after making sure it was safe I let my 16 year old try it at 50 yards. Shoots 4 inches high and 4 right, but his group was around three inches with Turkish ball ammo. Those sights are for the young!
