Good morning everyone

I found an LP with a hand-written label and the record company is not there.
Perhaps one or two or three of you folks can tell me.

The title is Mozart: Serenade in C minor for wind octet.
The conductor is Henry Schuman.
The scratched writing just outside the label says DBH [this I know to be the late David B. Hancock, sound engineer of NYC).
The catalogue number is DC562.

Can anyone tell me what label that should be?

Thank you.
Ben Roth
