This is a great little shop, little being the operative word. I've been there a couple of times and even bought a few loose, complete figures and a couple of comics from there. Can't remember the guy's name but he's a nice bloke and prices are negotiable. I'd have been half a dozen times but his opening times are very limited so be aware. I think Saturdays may even be "appointment only", really can't remember. Anyway, give him a bell to be sure he'll be about as he does do some trade fairs.
In terms of vintage SW he doesn't have a great deal. There was a reasonable boxes AT-AT there (talking 12 months ago) but that (still) wasn't for sale and there had been a 12" boxed Denys Fisher C-3PO at a very reasonable £70 which I kicked myself for not buying when I went back the next time and had gone. He had a fair selection of loose complete figures (nothing amazing) but there was definitely some repro weaponry with some. He's open to that and doesn't mind you swapping weapons (as I did ) if you ask. He said he doesn't add them just puts them with what comes and leaves it to the buyer's to decide. I guess if SW isn't your main area that's not unreasonable.
Anyway, enjoy. It's a really nice little shop with some great vintage toys.
