The LP-21-?? in this auction was normally used with the SCR-269-* (BC-433-*) and the AN/ARN-7 ADF sets.  I suppose it could be used with the post-war Bendix commercial version of the AN/ARN-7, the MN-62 (not 26).

The MN-31 is basically a MN-26 plus external Loop Controller. Didn't the ARN-6 or 7 use a ferrite loop in a glass dome?I cant say 100% but it sure looks like it, except possibly for the connectors.. Mine is not to
hand. I'll look for the MN-31 manual later tonight.
