I have a copy of Eric Dolphy's Outward Bound on a gold label Prestige. It's not mentioned in the Goldmine book.
That's 7311, another with no release date listed.

FWIW, the Schwann listings were dated when first published. The issue date was often 2 months earlier. Schwann also asked for promo copies to "verify information". If you sent the record the details were printed, if you didn't they only listed the record. In the early '70s while managing a chain of record stores in Boston I discovered the reason for the demand of promos - William Schwann would drive up to the store's front door and sell the records out of the trunk/boot. What a creep.
