Inductor 40-1925? Looking for info

[John H. Klingelhoeffer]

I know this is sort of a 'reverse' question, but let me post it,  anyway.
 
Anyone know what a 40-1925 inductor was used in, and what it's specs  are?
 
This is a small, shielded 7mm size transformer (5 leads, 4 active), with a  
primary and secondary winding.  Much like the inductors used in the VF-2031  
(which used a 40-1926, so entered the inventory in the same time frame- probably 
 around 1978) and the much earlier HW-2021.  No apparent internal  tuning 
capacitor - must have been external.  
 
Guess I'd just like to know if it was for 455 kHz or 10.7 MHz and what the  
transformation ratio is.  Yes, I can do the measurements and figure it out,  
but better to ask than to reinvent the wheel.  
 
Thanks to all in advance.  I'm cleaning up the junque boxe and want to  know 
if it's worth keeping or not.
