Duane, Here's the reply I posted on the Traditional ML Forum:
This may not be much help, but one of Sam Fadala's BP books (softcover) has photos of that rifle. You want the book with the photo of a brass framed Navy Arms Leech & Rigdon (?) revolver + can of Goex on the cover: 1982 or 1983 edition I think.
And yes, it was produced by Ozark.
