The 20's era dominates with the oldest sax mentioned being 1916 and the newest of the old from 1937. There appear to be fifteen different names on the bells. Farina_man claims the largest selection. And thanks to Lydian for the YouTube video featuring the 1859 Adolphe Sax.
I think the spreadsheet could be downloaded and updated by anyone here. I don't claim any particular ownership of the data.

I purchased my Zephyr because I perceived it as an upgrade from the Cleveland 613 and, for whatever reason, wanted to stay "in the (King) family. That's the only logic that I can remember employing.

JayeNM makes a valid point as to playability of horns from that era, which is countered by Lydia's video of the 1859 Adolphe Sax model.
Great input, everyone!
