If you look back through my various blog entries about the Kingswood, you’ll see that I started with some wrong ideas and gradually worked towards more apparently correct ones with the help of various readers.
There are still some questions, though. It seems clear that at different times the Kingswood was manufactured by Valentine, Langs and Unique. Regardless of who made them, they seem to share material with Valentine/Parker. Not exclusively, I believe, as I’ve seen one or two patterns in Kingswoods that I haven’t seen anywhere else but in general there’s a lot of sharing of celluloid going on. How did that work? Were rods of celluloid handed over with the contract?
Why was the manufacture of the Kingswood contracted out at all? It’s perhaps understandable that in the days when the brand was owned by Eversharp which appeared not to have manufacturing facilities of its own that the work should be farmed out to other manufacturers. After Parker acquired the business, though, one would have thought it would be more efficient and economical to do the work in-house at Newhaven.
