good doubles at any thing other than a collector's show might be rare. The kit is in the truck in case

i put my kit together after passing on might have been a really great deal for a Parker hammer gun at a antique show (the too perfect bores concerned me). and have used it at such shows since. Although I am surprised at the gun dealers who cannot answer basic measurement questions- the average antique dealer will not even know what you are talking about. i have never had one refuse to let me measure, and most are interested in what i am doing.
