Can anyone identify these portable motors/motorboards?

Hi all. I'm a bit overwhelmed / excited to be going through a lot of phonograph parts that I purchased across the cheddar curtain yesterday evening. Huge lot of parts, besides twenty-six clockwork motors to identify. Most of what I've got is Victor and H.G. Saal, but I'm having a hard time with these. No identifying marks. Anyone recognize them or what brand they were likely pulled from?

 

Thanks!

Judging from the response, I doubt they are a common, identifiable design. I've posted these today on eBay if anyone happens to need them.
