I think they're listed under specific Crosman models, which are duplicates.
Crosman and Daisy also made several air guns for Sears including a 760 model.
I think collectors that think that way will wish they hadn't in 20 years or so. A special model is just that. Period. And the Revelations were tricked out with all the extras, as Western Auto usually wanted them. Rifled barrels, different stocks and the like. Now if I could just get some of those round tubes for the front sites. Missing those on both my 760 Revelations.
I've trimmed up a powerlet to use as a front sight hood. Worked well. Dave
