[time-nuts] Racal 485 1MHz frequency standard

[GandalfG8 at aol.com]

Hi All
 
I've been offered a Racal 485-1, 1MHz frequency standard and  distribution 
system.
>From the photo it's basically a Racal 1MHz ovened oscillator with a 12 way  
distribution section based on TO92 style plastic transistors.
I don't know that it's something I'd use these days as a lab  standard but 
might be interesting just as a curiosity, and the distribution  section does 
take an external input.
I've never seen one before, nor even heard of it until now, so would be  
grateful for any information that might be available.
 
regards
 
Nigel
