Pape guns vary in quality - many of his guns are Birmingham made guns that he finished in-house.
Pape had a genuine style about him and some of his best guns are outstanding. He was not averse to unusual engraving and fanct checkering patterns - especially on hammer guns.
Pape was of course credited with having patented choke boring in the UK, thoug it was Greener who developed it properly and saw the potential it held.
I have some nice photos of unusual Papes I'll e-mail them to you if you like as I'm too stupid to manage getting them up on site.
I doubt you'l be disappointed in the gun if you get it for a fair price.
