Please note: I've relisted the seatpost on eBay to reflect the fact it is not NOS as previously thought and is now accurately...
Thinking about it, I'm pretty certain it has never been inserted into a frame by the looks of it but from what you pointed out, it appears to have had a seat attached. That's my best guess.
Hi, I have just the thing you are looking that will go live on ebay this evening. I'll post a link in the market place section when it goes live. cheers, dean.
