I've recently bought a BSA Monarch (1st Pattern) with the integral 19mm rails. It's currently fitted with a 26mm Pecar in Parker Hale mounts. I'd like to mount a 56mm 1" scope on it if possible, but need higher mounts. So that I can start the search for alternative mounts, has anyone seen a list of all the different Parker Hale mounts and what they were manufactured for? I'm getting baffled by all the RAN4, RANS5, RANS2, RAH3 etc. codes and need some sort of list or catalogue.
