Cleaning up the ham shack and found these two items - would like to find a home for them so I don't do something stupid like taking them apart for the parts. These are apparently nothing more than impedance converters for headphones (e.g. HS-33). Order number on one is "148-DAY-44" which  I assume that the original order was written at the tail end of WW II. Just cover the postage ($8??) plus a couple of bucks and I will be a delighted ham.
