i have a 20 gauge white powder wonder shot gun patent date 8/12/1913 any idea what it is worth
it was probably made by Crescent out of Mass. or CT. can't remember which. It's a chain store gun. White powder refers to smokeless powder as opposed to black powder. It probably is shoot-able, but I wouldn't shoot it. If you can find somebody that will give you a $100 for it, take it. I work part time at a local gun store and we won't give more than $35 for firearms like this.
Would you be interested in selling the gun?
