mystery bass currently listed on eBay? I'd guess that it was from the 1960s - it's certainly no later than that decade. Note that it has a single pickup mounted near the neck, tapewound strings, and a cover over the bridge; all features that help date the instrument.
Currently listed on eBay with a Buy It Now price of $650. Thanks to Kalle for briging this bass to my attention via our Facebook page.
