By way of a trade, I have a Beeman C1. Actually made by Webley. No expert on which model Webley, and really want info, please. It is in .177 caliber, and despite the photo, it is clean. No rust, finish mostly correct. It is going to a tuner soon. What is worth fixing ( trigger pull) and ? I will be repacing seals, breech, and piston. Also new spring and lube. What practical range do these rifles shoot? Maybe as well as my FWB 124D, HW35E, and HW97K? I have never had one. Back in the 1980s, my buddy had one, but I never shot that either. Any real help or knowledge?
