picked these up from the charity shop lunch time today - I think they are the real thing, but not sure how far into the C20 this sort of style went. Intriguing, because contrary to what I though initially, it is only the threading that is opalescent, not the whole of the upper body. Pontils are snapped very cleanly, and there is a considerable 'wear ring' to the underside of the foot. Can't see anything that matches in the few books I have, but understand names like Walsh, Stevens & Williams, and Richardsons cud be pontential candidates. There's no response under u.v. 15cms. tall, and about 12.5 cms. wide at the mouth. The scallops are very C19 of course - just that I thought couldn't be my luck to find a pair - undamaged - after all these years. Oh, and by the way, they were a quid each. thanks for looking, and obviously I'm hoping for confirmation that they are real. cheers Paul S.
