Hi Selfbow, sorry to bump up an old thread, but these 1047's were made in 1965 and '66, maybe some other years, I don't know.
The Golden Sovereigns are listed separately from the the Ben Pearsons at the Archery Archives site. I'm not an expert or anything, but I just got a model 1048 and saw it on the same page as my bow. I'm searching for info about my bow and saw this thread, so I figured I'd pass it along just in case you're still wondering how old it is.
The '65 model was rosewood (I think there are typos @ archery archives, it says "roseool") and the '66 was made of treijo (which I guess is supposed to mean freijo?)
It is a beauty!ope this helps
