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).
