What we have here is a Robinson stamped (lightly), cromo, layback seatpost, that has been cut down. Got it in a box of parts just the way it is pictured. As the photo shows it is about 10 and 1/4" tall. You can also see where the upper end has been 'profiled' to fit something. It is a bit out of round at the top as well.
I have no idea what it is worth, but if you want a Robinson seat post and don't want to run your seat in the nose bleed position, and don't want to spend twice as much, maybe this is the post for you!
