I have a junk M-14 FPR typing reperf 
(except the whole typing basket is gone!) 
so I was checking to see if the selector 
magnet coil(s) from that were interchangeable 
with the M-15 selector magnet. 

An interesting quirk I found .... 

The M-15 'holding magnet' coils are numbered 
M-207 with a 92 ohms per coil spec; 

The M-14 FPR magnet coils are numbered 
207M with a 550 ohms per coil spec. 

Hmmmm.... duh ...  seems weird to have two parts 
with such similar part numbers.
