Thread Name: Harmonica keys available in early days
Subject: RE: Harmonica keys available in early days
I figured one way to answer that might be to google for early issues of the Sears catalog, since that's where most of them would have come from - but I can't read the pages well enough on my phone. Didn't see anything about key at first, though.

Ocarinas were made in a huge range of keys from the very start, over the same period, and they were aimed at a similar market (proletarian and portable). I'd expect that harmonica makers went some way down the same road.
