I have a Model 94 produced around that time. When I had a Williams
Foolproof sight installed, I found that the receiver was already drilled and tapped for such a sight from the factory. The receiver sight makes the rifle much easier to shoot accurately than the buckhorn open sights that came on it. I bought mine used at a gunshow almost 20 years ago for $150.00. It was/is in almost new condition with a perfect bore and only a nick or two on the wood. I imagine that I could probably get a little more for it now than I paid for it. So I guess you can expect your 94 to slowly appreciate over time. Personally, I would use it however I wanted to and enjoy it without consideration of it's collectibilty status.
