I've had a Hering low C for about 10 years. Finally had a couple of reeds replaced a few months ago. Good Low C harp. I bought a lot of the Vintage 1923's for about a year. Nice look and heft but the reeds were very soft and blew out very easily.
Good luck and have fun with that harp! ---------- Music and travel destroy prejudice.
Big band stuff works well with that tuning. Will Galison uses it upon occasion. I like bebop--you are close, it has a Bb instead of an A on hole 4 blow.
