Rob,I love my pre-war Webleys,I truely do.But if I could fit them all out with .177 barrels I'd be happy. The firm eventually strengthened their .22 barrels-but not quickly enough. Design-wise,the J/F/C idea was grand.They came up with the "RR"of airpistols! As far as I can ascertain,Webley pistols are more envied than mocked.Not withstanding the fact the MkI pistol is as difficult to cock as the Senior,Junior and Premier are easy!Regards,Trev
