I could see Blue Magoos; same w/ The Blue Things (later Fyre). I hope it's not Blues Breakers, because fuck Clapton, but at least Kevin Gray did a Sundazed remaster a few years ago to lessen that possibility. Of course, you also have a Sundazed/Kevin Gray with East-West. If it's a bigger name like Buffalo Springfield, I won't be surprised if VMP jumps at the chance and ignores recent US reissues.
If we consider just album title there's
Barefootin' by Robert Parker; supposedly a reissue out there but can't figure out who did it
Black Monk Time by The Monks (reissue in 2016 by LITA; pricey now)
Boom by The Sonics, no US vinyl reissue since 1998
