I think I may have asked this before, but I have a ca.1940 Holton 5 valve that has the wrong valve cores. Are there any custom shops out there (Midwest) that could build new cores? Thanks for the help. —-Macs Band.

Welcome back to the active side of the forum! You may not get flooded with answers because this is a tough issue, and probably not cheap.
Have you checked this guy out? He's one of the best out there for such custom work, as far as I know. It might be a place to start at least.
