The original Golden Age Arms Co. that I'm familiar began business on High Street in Worthington, Ohio, next door to the Historic Worthington Inn. There was a lawn area separating the inn from the building Golden Age was in, and a large cross section of log was set up for tomahawk throwing. The Golden Age as a Muzzleloading store was a changeover from a vintage bookstore, presumably named Golden Age. James Johnston was the owner of Golden Age Arms, and an elderly lady named Annie (don't recall her last name at the moment)worked there behind the counter. I learned later that she and her husband were the owners of the Golden Age Bookstore.
The shop was small, and I spent a lot of time there in the afternoons after school chatting with Jim and Annie, and occasionally getting loan of a tomahawk to go out and throw.
The shop was small, and always had a selection of a small handful of rifles, presumably made by Jim, and other local craftsmen.
My Dad bought parts to build a rifle there, which he completed in 1970, and I got parts there to complete a percussion pistol completed shortly thereafter.
I did occasional brass casting finish work and also made some silver inlays for Jim.
A gentleman named Tom White visited the store on occasion and was interested in parts to build rifles. He went on to build outstanding quality rifles, and as I recall was commissioned by the NRA to build a rifle presented to a President or notable person. I don't have any other information about him.
After I left Ohio in the late 70's I lost track of Golden Age and Jim, and heard at one point GAA relocated to a location in Delaware Ohio where they had a larger shop and apparently did a lot of on-line sales.
From what I can tell, Golden Age Arms is long gone, their Shop apparently closed sometime in 2005.
If the rifle you're looking at is elaborately and well carved, it may have been built by Tom White. If there are any tiny silver dogwood flowers inlaid in the wrist, they are the ones I made.
