[GreenKeys] Does anyone have info about RTTY Electronics?

Hi!
 
I'm looking for a gear to get my Teletype Model 28 LABD-500 (Automatic  
answer-back unit) for 45.45 baud operation.  
 
I've checked with Fred at Typetronics and he doesn't have one.  
 
I was thinking that RTTY Electronics might have it but I don't have a phone  
number, web site or an address.
 
The gear is TT Part # 305044.
 
Thanks and 73 de Russ WA3FRP
