I have no idea what its worth but about 30 years ago TNT built a PPC on a model 10 for me the gun was fantastic smooth and accurate. Used to take it with me when I traveled and shot informally with a few friends once a week for several years looser bought dinner, I never bought dinner.

I think the name of the shops owner was John Toll not sure of spelling or what ever happened to TNT.
