I may have asked this before, but what do the numbers means with the Conn sousa models (ie. 14K, 20K, 36K, 38K, etc.)?

Here is a link to a table that's under construction on the Conn Loyalist site that has most of the models listed: https://cderksen.home.xs4all.nl/ConnSousaModels.html" target="_blank

This is a great chart! Thanks.

I thought Conn was kind of notorious for their determination to lose track of things? Anyway, if you're looking at newer instruments other than the 20K, it's worth checking to see if it's really the indicated (older) Conn, or if it's a King.
