[Premium-Rx] Regco receiver info request

[Terry O']

Does anyone out there have any information on either the Ralph E. Grimm 
Company or Regco RG-5540 or RG-5545 receivers?  Anything would helpful.  
I already have the brief material printed in several Jane's Military 
Communications.

I'm currently corresponding with engineers who designed these radios.  
None of them saved any documentation or pictures.  I saw a listing for 
an RG-5545 that sold in the South Pacific years ago, but was unable to 
reach the seller or the buyer.

These are rare beasts.

Thanks,
Terry O'
