Thank you very much for the corrections - tried to implement them. Unless I know who made the lenses I'll keep Houghton & Butcher on though... because these early cameras have lenses with unknown manufacturer as far as I can see... if someone knows more about that, I'm happy to change things though. Also Kershaw: I feel like I've read that they made projection optics... or has someone else been behind those as well?
Added some more lens manufacturers I found a long the way as well as Mark's suggestion
With great knowledge comes great curmudgeonliness.
From a list of optics with names that sound sus in English, you're welcome to add 'Bender Optical Works' of Newcastle, UK. See also 'Nooky' (Leitz) and 'Veginar' (Pluscanar of Yugoslavia). Perhaps others know others . . . ?
Thank you! The Pluscanar and Veginar were made by "Vega" if my information is correct. Listed them under Slovenia.
