Six as of this afternoon.
Stopped into a local reloading supply store at lunch today that also sells a few guns and they had an old 16ga model 500B that just came in on trade. Took it off their hands for $160 then immediately exited the premises before the police got after me for stealing it.
No serial numbers, so sorry
@old mossy and
@blacksmith no dating on this one other than knowing it's pre-68. Has the 28" mod choke barrel with original wood including the old rat tail forend. Receiver is not drilled/tapped and there is only one bar on the slide tube. Blueing is in impressive shape and there are only a few scratches on the stock. The jeweled bolt has some minor surface rust that shouldn't be an issue to remove. This thing has the smoothest action I've ever felt and still locks up tight as a drum. Had to get back to work, but I'll post up some pics this evening.
Guess I need to stop complaining about not finding any decent deals on used 500's around here...
