Gabler conflates the United Hot Club reissues with the bargain bin stuff more than once. Short take:

“Milt Gabler: I first met Billie (Holiday) when she would come into my shop on 42nd Street with Teddy Wilson. John Hammond liked to come to my shop because I had bought all the old Okeh records when Charlie Stinson was the contact. I went up to Bridgeport where Charlie warehoused records he picked up from dealers around the country and cherry-picked the ones I wanted for the store.”
