I'm sure this response was well intended, so thank you for that and for the 
 advice, but I do feel that Attila's earlier  reply explained my reasoning 
remarkably well.
Under consideration is the taking of a very nice example of  an older and 
now unusable off air frequency reference, a little bit of  interesting 
history perhaps, and putting it back on the air without any  form of internal 
So what's the point?
Well that's it, other than the satisfaction of doing it there really  is no 
point, other than perhaps, to quote one of my wife's favourite sayings,  
"just because":-)
Time code receivers are not really my thing, each to their own I  guess, 
but a no doubt somewhat unhealthy obsession with  reasonably precise frequency 
generation does mean that finding a more modern  frequency source to drive 
it may not be too much of a problem:-)

What in the world would the point of that be!?  It appears to be a  
long-obsolete product, so have you searched for more modern time code  
receivers from timing instrumentation (Meinberg, Brandywine, et al.) and  
surplus vendors?  It'll probably be pretty expensive, for it's probably  
much less popular than WWVB and DCF77.  Have you tried the  latter?  It 
might be receivable from Britain, and I've seen some  surplus DCF77 
receivers (e.g., an old ISA  card).
