The links worked brilliantly, thankyou. It certainly looks like the same building in the close up photo and I presume the big store was one of the two large buildings to the left of the one I'm interestsed in. I'm wondering now if he may have been in partnership with them and decided to branch out on his own. I wish I knew why the big leap to Yorkshire though. he kept a diary in the 1920s and 30s but there's nothing about his early life at all.
Still, it just makes the challenge more interesting doesn't it.
I'll post a new message about Trade Directories and see if anyone has one.
Thanks again for all your help, you've certainly moved me on a step or two, if I can do anything in return please let me know,
Hilary
