Mike,
 
I have several selsyns, but all are 115v 60 Hz types - I think you  will 
find that the voltage on yours is also 110v, but at 400 Hz (aircraft  
generator frequency) and dropping the voltage to 57 vac 60 Hz was necessary to  
limit the current and heating.   I have a pair known as 5 pounders,  they are 
about 3" in dia. and 6" in length plus shaft.  I also have small  units about 
1.5" in dia. and 3" in length.  You can mix and match with a  little 
balancing of voltage.
 
Give me more details of the dimensions and maybe I can match up  something.

Thanks.
