I’ve got an extra dr Pearson Rossi 92 scope mount here I forgot about unit I saw this thread. If interested pm me and I’ll give you a better deal then ordering on from the USA. Have a slightly damaged skinner rail I can toss in too. See my botched drill and tap thread under gunsmith subforum for pics of that.
Edit to add. There’s an old gunsmith here in Warren ont that has a box of mounts that fit into the 92 dovetail. If you want his info pm me.
