I have just seen this nice Rigby boxlock offered at an German auction for sale:

It has ejectors, new barrels made in 1988, first-class condition,zeiss scope with claw mounts, original case with all accessoires, built in 1920. Seller claims it shoots very good.

Looks nice but I am in negotiations for another fine double already.
