Sorry, I got the model confused, it's a Blackstone, not a Zenith.
My friend and legendary NY swing guitarist Chris Flory, sideman to such greats as Benny Goodman, Scott Hamilton, Ruby Braff, Harry Allen, is selling an old road guitar of his, an early 1950's Epiphone Blackstone, with a retro fitted DeArmond floating pick-up. He bought the guitar from Duke Robillard (they go way back to the jump blues and swing scenes of New England in the early 1970's). He wants $1500. for it. It's a great guitar and comes with guitar royalty provenance! Contact me via PM or email if you're interested.
PS: For your enjoyment, here are some vids of Chris:
