According to discogs, one sold for $51.95 in August 2019. There's no mention of condition though.

According to the liner notes of the "Jack Ashford Just Productions" CD on Kent, the London based MAM label did strike a deal with Jack Ashford to lease product on the MAM/ Magnificent/ Miko labels.

According to an article in "Soul Survivor", Jo mentions Ruby Andrews "Casanova" and all of Garland Green's work with Jo as being cut in Detroit. I think all the Armstead / Terry output was done in Detroit.

I don't think RCA Victor "bypassed" it's promotion stage. I think they just sent out black stock copies as promos. Once in awhile, you can find one like this which reads "Many Thanks Stan Pat" who did do promo work for RCA. Whether or not anyone would consider this a promo is debatable.

Just to clarify- are you saying RCA didn't release promos before 1954 ? Here's one from 1951-

I think the 45 came out in late 2019. New Zealand Soul (?) -
