I ran across this Belgium made antique single shot 22 RF There is no maker marked on it. There are two screws missing along with the breach block. I'll make these parts. Barrel is so-so. Does anyone out there know what I have and maybe a value? http://www.firearmstalk.com/forums/members/mcskipper/albums/very-old-22rf/2364-img-3/ hope the photos show-up!
