I do a little a lot of random Googling. For some reason, I got to a thread on SOTW about the Conn (and Buescher; including some stencils for each manufacturer) Polychrome finish. "Chrome" was a trade name for a mono-chromatic enamel finish and "Polychrome" is the trade name for multicolor enamel. I've seen a few of the former and two of the latter.
So, my Googling led to The Music Trades magazine from 1923 -- and there are a bunch of those magazines you can download. There's a write-up on the Polychrome horns and a couple comments on the microtuner neck. Enjoy!
