Zenith mainly used V-M; RCA built their own for a long time.
G.E. bought Glaser-Steers and produced a variant of that changer for several years.
Webcor was another supplier for Philco and many others.
BSR really became widespread in the early 70's as other manufacturers ceased production.
Garrard changers were quite common across the board.
As far as I can remember, Magnavox was the main (if not only) one that used Collaro changers.
