[Amps] looking for choke specs

[Don Lemley]

Hi all,
            I am looking for specs for a choke that I recently picked up
from the home of an SK, who was famous for building
            big amps, but this looks to be pretty average sized, and I
might like to use it if I can just figure out the details.
            The Mfgr appears to be "MTC", like maybe Milwaukee
Transformer?  and if I read it right, the part number is one of the
            following:
 
            L-73622 or 056-000681
 
            The complete label looks something like this:
 
            056-000681
 
                MTC
 
             L-73622
 
                EIA 
 
            and there is a hand stamped date code? of  "64  17"
 
            I'm guessing this puppy weighs in about 10-12 lbs.
 
            Anybody got any sources for something like this?
 
            Thanks,
                        Don - W8HRQ
