There you go Nick
I gave up on you buddy. Figured you might have been frightened off. Ah well, that's what bike forums are for, another happy member, and they where an absolute steal. Not my cup of tea, but I was very surprised they lasted so long.
As for the seatpost, you just missed a NOS 1 on ebay 2 days ago. Best of luck in your hunt, and hopefully by now you know how to look for that elusive seatpost / 50th kit. You have to actually go to the foreign ebay sites, then type your search.
It can be very tiresome, tracking rare stuff, even more so when you get outbid with 1 second to go. Thats why your wheels where an absolute "get them whilst you can", because a BIN meant no being outbid.
Take buddy, yours Laz.
