Hello to All

I need a operations and service manual for this HIckok transistor tester AN/USM-206A it hasn't worked since I got it. I would greatly
appreciate any help finding this manual and will gladly compensate for time and materials as needed. Though my search I did find a resource that may be of help to members of the forum looking manuals,  navy-radio.com  listing equipment from 1950- 1960's you can down load free, unfortunately not the 206A

Thank You in Advance
