I'm looking for the year of manufacture for Baystate Banjo serial number 301, which a friend found in his dad's attic. It has enough dust on it to show it is at least a few years old. The brand and serial number are stamped on a square wooden dowel. The manufacturer is harder to read, also stamped on the dowel. May be Haynes & Co. or something like that. It was manufactured in Boston.

Does anybody know about this Baystate brand or where on the web to find a list of relevant serial numbers?

Thanks,

Jonathan
