Value of single shot, 28 ga. shotgun (with hammer)...

I have a single shot, 28 ga. shotgun (with hammer). Information on the gun is: J.Stevens Arms & Tool Co.
Chicopee Falls. Mass. U.S.A
*Electro Steel * Choke Bored *. Any, information as to history and value will by appreciated.

hello..in 28 ga it's kinda rare for a stevens single shot ,, but not real expencive and shells can be a problem at times to find ,,not many discount stores sell 28 ga ,,but it is an oddity of sorts for a stevens and i'll say it's worth 150-175 just because of the guage ,,if it were a 12 ga value would be around 75-100,,
