They also have an interesting Bristol 400 based 406 zagato (Aberdeen Registered), a load of Bristol spares with a derelict 406 and a AC Buckland for sale.
I did see on the website you can register for I bidder/online bidding but its not clear if that counts as an absentee bid & is subject to the deposit.
£1000 might be cheap in the long run Malcolm to stop you buying stuff you don't need.......
The deposit might also be to avoid non serious bidders/avoid the ebay ramping position.
