GUEST, Colin Holt:

Could the shop you refer to be "Kitchens"...

Kitchens! That was it! Thanks for bringing it back to me. The shop had such a great reputation at the time (early-mid '60s) that it was worth the rail trip across the Pennines from Lancaster to browse it.

The other northern shop that had a big reputation at that period was Mamelock's in Manchester.
