Well, that confirms some suspicions. Possibly a WWII trophy but I would think it stayed in Europe till the rebarrel. It is possible that a GI poked it in a duffel and brought just the receiver home. Then spending quite a deal of money, he had the additional tubesets made in Liege. Maybe he was stationed in Europe and more easily sent it to Liege?? Any history on the previous custodian?

Cheers,
