If sound exchange cant help then call banana records in st Petersburg on 22 ave . it the largest in the us for vintage record and hard to find records
Exactly what Michael said they'll know exactly if they have them but also where you could get them if they don't know. Very knowledgeable people great store wouldn't doubt if they do have some more looking into it if there's a need for those around the area.
I would call sound exchange both locations the employees are super knowledgeable and will certainly point you in the right direction
I wish I could help with your very interesting question but, I can't.
