1951 BAL-AMi Model D
This is a photo of a USA AMi version of the Model D, courtesy of Pat Reese.
The Model D is reported to have been sold in the UK by Balfour, and was included in "The Ultimate Jukebox Guide" book. I've added it here for completeness, but have no evidence of any Model D ever having a BAL-AMi ID plate on it. It's possible that Balfour kicked off the relationship with the USA AMi company by just acting as a distributor for this model initially.
