Some research tells me there was only a handful of jazz albums on the Vault label:
108 Jack Wilson - The Jazz Organs
131 Elaine Brown - Seize The Time
9004 Charlie Barnet - Charlie Barnet Big Band - 1967
9009 Hampton Hawes Plays Movie Musicals
9010 Hampton Hawes - High In The Sky
9012 Charles Owens - I Stand Alone
9006 Kid Ory - Live
9001 Jack Wilson Plays Brazilian Mancini
9002 Jack Wilson - Ramblin'
9005 Larry Bunker - Live At Shelly's Manne-Hole
9008 South Frisco Jazz Band
9011 Ernie Watts The Wonder Bag
An elaborate listing can be found under http://www.bsnpubs.com/la/vault/vault.html
Ramblin', the two Hampton Hawes and the Larry Bunker (with Gary Burton) have been reissued on Fresh Sound. The Ernie Watts is a poppish treatment of Stevie Wonder tunes. The Elaine Brown is a poetry recital with jazz backing arranged by Horace Tapscott.
The Barnet big band has Jack Wilson on piano, arrangements by Billy Byers and Bill Holman. The Kid Ory is a 1947 live recording. Can't say anything about the South Frisco Jazz Band, probably a revivalist affair. Charles Owens was a West Coast hard bop tenor saxist, Oscar Brashear plays on his album.
Other LPs in the 9000 series were pop, e.g. 9003 by the Chambers Brothers.
