Need some help on trying to figure out the age of this Washburn 5 string open back banjo with serial number 1641stamped on the neck rod. Any help would be appreciated.
A precise serial list isn't available. The Washburn book estimates that banjo serials were in the 900s-1000s around 1896 and in the low 3000s around 1913. They restarted the serials around 1923, but an open-backed 5-string is probably from the earlier period.
