[Edward Tinker]

If you buy the book by Reese (sp), it tells assorted information in detail. {{hopefully others can help us??}}

although it sounds like you have the answer and are looking for confirmation?

The "true" cartridge counter guns are worth a pretty penny, and I don't believe that many exist still. I am out of town, so do not have access to my books.
Hopefully someone has the info you are looking for? Although it would be benificial if you provided further information on what you have?
