WTB: Thomson layback lower cradle

Hi,

I'm looking for the lower part of the saddle clamp for a Thomson layback
seatpost, silver if possible. I don't know if this differs from the
corresponding part on the inline post. I also need one Thomson bolt and
(more importantly) its barrel nut.

I know these are available retail but a) they're hard to find in Europe,
and b) I'm a cheapskate.

Thanks,

James Thomson
