Did any member of this forum work in the developing and printing trade? Some companies diversified into specialist services to professional photographers like John Slater Photography Ltd of Newmarket with their Colorlabs International subsidiary.
Do you remember the Kenprinter? This was made by an Ilford Ltd subsidiary called Kennington and Bourlet Ltd who are bizarrely not mentioned in "Silver By The Ton" the history of Ilford Ltd. Have a look at :- http://www.greatyarmouthphotographic.co.uk/ilfordltd/page11.html
So if you remember the Kodak Velox Projection Printer, the Williamson Enprinter, the Ilford N Printer, the Kodak Colour Printer models S1, S3 and S4, processors made by Wainco or Pavelle or any piece of D&P gear then do contribute to this discussion with your memories and anecdotes.
