Also welcome on board John ... but you are going to have to enlighten me as to your moniker CLYDEBRAE for a Preston lad!? (even with Ben Line connection the other side of Scotland!)
Sometimes I wish I had a decent memory! I am scratching my head trying to recall why and when THPA utilised Impex House. I think it was only briefly, and it must have been back in the late 70s/early 80s (after ICI?). I know I went across from Queens Square to see somebody there but .....! Just wondering if it might have been in the aftermath of the Peckston collapse (was that 1979?).
.... and now, not sparing John's blushes, I have found the Cockfield Knight history at:
http://www.cockfieldknight.com/index.php/history
It answers my Peckston question. (1980).
Arising from that article, I can also say that somewhere down the line I gleaned a copy of the Bulmer's Blue Book of 1926, including a photocopy of the letter dated May 1926 they sent out with that booklet.
