[Milsurplus] RBA-RBB-RBC receivers

[Mike Durff]

As a courtesy, I would like any and all owners/users of these units to voluntarily reply to my email mikedurff at yahoo.com. I would like to compile an inventory of what's out there and the condition of the survivors.  What prompted this request was a current listing on ebay showing an RBC with RBB nomenclature tags. 
This is not for any personal gain to me. I would just like to keep a running list showing the disposition of these fine old receivers.
Thank you, Mike Durff
