In the back streets of Weston-Super-Mare, I spotted a Hornby logo on the front of a shop that at first sight, didn't look that promising. The front suggests once of those places where you trade in electrical items and computer games, and they do offer this service, but also a lot more.
Inside, this is a big shop. Turn right and there are many (locked) cabinets of model railway items, mostly second hand. There were Graham Farish OO gauge wagons in a cabinet. I looked and they were priced for proper collectors and not casual ones, but how often do you see these?
There are normal RTR model railways and plastic kits plus a very well-stocked Humbrol paint range. There's also Citadel to go with the Games Workshop figures. In fact I was a lot more impressed than I'd expected to me. OK, these guys aren't specialists, but the shop is well worth a look if you are in town.
