I have the quarter plate Houghton Victo, quarter plate Houghton King enlarger, Ensign safelights - 2 glass to take standard bulbs, i candle powered, to go withnthat tank

I could have a complete early 1900's Houghton darkroom. I have the 3½x2½ version of the Klimax tank.
Ensign is Houghton's main trade name and they owned a number of companies, by 1910 they had a large factory in Walthamstow, the buildings covering 2.5 acres.
Klimax was a name used by Butcher for cameras, tanks, printing frames, printing boxes etc. Butcher manufactured some items for Houghtons and both companies formed part of British Photographic Industries Ltd registered in 1915, but they already had a joint Houghton Butche Manufacturing Co, Houghton and Butcher traded under their own names despite joint ownership until merging into Houghton Butcher Manufacturing Co in 1926.
There's an important US link, a major shareholder in BPI was
Lord Astor and his family, born in the US & moving to the UK at the age of 5, he owned the Times newspaper, was a banker, politician etc etc. He was probably behind Houghton establishing an Indian subsidiary company as he was Aide de Camp to the Viceroy of India j before WWI.
