Make of this what you will:
5 VINTAGE IBM TYPE M KEYBOARDS ☆make me a offer ☆ BIN: $400 + shipping
That's definitely a
Model F-AT at the top... The other four appear to be p/n 1390131 (first-generation) Model M's.
The seller says "Make me an offer", but there's no "Make an Offer" button, so I guess they expect you to to message them. (They've been on eBay nearly a year, have 34 sales and 100% approval, so they seem on the level... Maybe they just didn't know how to activate the MaO feature.)
Considering ATs go for $150–250 these days, and that '131s are
as solid as M's get, this could be a very good deal.
