[Hallicrafters] SR-500 Question

[Ed]

OK, it doesn't exist or there was only one, or three, or five built. N9CQX 
tells me he has one he doesn't want to sell. I know where there is an empty 
SR-500 cabinet, because I bought the HT-30 out of it and the guy has refused 
to sell me the cabinet (so far) because it will mean completely rearranging 
his radio room.
One sold on EBay last year for $800+ dollars (I saved the web page). And 
there are Hallicrafters ads for it in CQ and QST. Whom are we to believe?
