Seat post size is 26.8mm. I have one that fits. It is a rare Birmalux (but branded 'Lambert') aluminium one that was fitted to Viscount Aerospace bikes. Trusty Viscount was created out of the ashes of the bankrupt Lambert of England bicycle manufacturer.
I could throw in the seat post for a tenner which is a BARGAIN!
