McLean,
That's a difficult question to answer. You have several considerations that will affect value. The first is not being able to identify the builder's location, next comes the overal condition, regarding the stock and the bore, with the stock being of more importance. In this case the stock appears to be in good condition with the exception of the forestock which is cracked although the wood appears to be there and could be repaired. It does have nice hardware. As strictly a "questimate" I would say that, around here it would bring between $500-$800. Perhaps more, perhaps less, that is just a questimate, from what I can see. Do not take my word for the gosple.
