I live near Northwich (about 15 miles from Manchester) and would like to give a mention to The Model Shp on Witton Street in Northwich. Run by Dave Smith, it's a very small shop which caters for model railways and wargamers plus a few Airfix kits etc. Dave has a good stock of all the regular consumables, paints, thinners, plastic weld etc as well as stocking a lot of Wills and Peco stuff. He is a friendly bloke and good for a chat. I go in also because he stocks Peco 009 and will occasionally give you a discount.
