Didn't this used to be Smiths, the ladies outfitters? They used to have one of those sheets of yellow celluloid in the window to stop the sunlight fading the stock. Anyway you are right, ddd, well done.
Now I know you've been following me.
It is not the Warrens to the left of the Wellington (i.e. 7 Market Square) but the shop to the other side of the Wellington (10 Market Square) which is also Warrens, although it is signed as Andrews in the photo' you have linked.
It was Warrens when last I visited it and still listed as such on W T Warrens website (as Top Shop 2). If anyone produces evidence. that I am out of date I will accept it.
According to the linked photo I placed on the comment it states the photo was taken on Tue Jul 5 14:26:11 2005.
As that was over 4 years ago and I am working from memory here (last visit to St Just was 6 months ago now) we should accept Chill's account.
