Looks like Kalloy. Barely used. Possibly removed from display; maybe on a bike. To all intents and porpoises, NOS. I basically got in the wrong size, (needed 26.6); call it poor attention to detail or whatever.
But I'll be taking a hit on it, as I got it from bicyclists_retreat in Kansas.
It's long-ish, at ~30cms. for the post itself. Looks solid/well-made.
