I just spotted this free site and they have almost every edition of Cash Box magazine - which you can search for names like Wurlitzer (and add 1015 or other models to the search) to see a lot of stories on Jukeboxes and their history.

They have a tremendous amount of information archived - for another example, have you wondered about who made various electrical/electronic components used in jukeboxes? Check out these Radio's (and Electronics) Master Encyclopedias:

You can get lost for days if you love research!
