Alan Larsen, United States of America (USA) - Tube collection

Below you find a part of the tube collection Alan Larsen.

I collect early 1920 wireless radios. I have a fairly extensive collection of early 1920's American broadcast receivers. Makers such as Crosley, Atwater Kent, Grebe and Tri-City comprise the bulk of my collection. I also have quite a few rare makers sets. Thanks, Alan
