As far as I can tell (from the pics)... it's an 8620A... and getting a scale to match the plug in is not a "... minor issue." (at least it wasn't for me.)
Am I missing something... or is there something special about this particular 8620. (Owned by Bill Hewlett?)
Despite the well staged, and sumptuous color photos... it looks like any other clapped out 8620X, one used to trip over at a ham fests.?
