That's impressive research, Shaun!  Even if you're wrong about any aspects of this brush, I believe you are in the right ballpark.  Lovely find!

Thanks, Brad, yes. Smile Naturally, I remain open-minded as to an alternative brush-maker, subject to newer information coming to light. It may take some time, of course. I'd have liked to have asked Mr Gary Young for an opinion, but that's not possible, unfortunately. In the meantime, here is an advert from the 1922 British Industries Fair for Erinoid (the British name for Galalith, post-1914 when production in Stroud, England, took off). Note that it specified the new product was suitable for turning (available in rods) and was a good substitute for bone, ivory, etc. As a handle-maker, I'd have been intrigued, and naturally, Erinoid had already been available prior to the Fair Smile

Now that's really neat, Shaun!  It would be nice to be able to order some Tongue

You won’t find many examples of shaving brushes with these handles. I think the reason might be because of the strange smell when it hits hot water! Putting it under your nose each day, despite some wonderfully lovely shaving soap... just a theory. Smile Still, strange how there seem to be almost no examples.
