I don't know if they'll have this exact model, but there's a great hobby store in Aylesbury, Buckinghamshire. I have to apologize, but I forgot the name of it-having moved away from there several years ago. I know they're about a 10 hour drive from you, but they may be able to ship up north.

Having been there several times, I have to attest that they carry quite a few foreign models/kits. If not in stock, I would lay odds that they could get it for you. Their store is probably one of the best in the London area, and is comparable to most hobby stores here in the U.S.

You could probably do an web search or get the telephone directory and find them.

Best of luck,
Troy
