It has the TCXO - I can hear the relays clicking  rhythmically.
 
Hi Hans
 
That clicking is most likely to be the hour meters on the back of the  
receiver.
It sounds random and mine were driving me crazy before I was told about  it.
Check in the manual, it will show you where the little connectors are  on the 
motherboard and you can just unplug them.
 
This set sounds very much like those released in the UK a while ago that  
were badged Marlborough Communications on the label you mentioned as  missing.
Several, at least, of the Marlborough sets were left with mil air  
frequencies programmed into the memories which is another clue.
 
The only thing that doesn't match is the 16 KHz bandwidth as they had a 10  
KHz roofing filter in the first IF.
You can check the roofing filter easy enough just by opening the first  IF 
module as the filter bandwidth is marked.
However, if there's only 5 filters in the 455 KHz IF module it could be  that 
the "16 KHz" position is actually just the 10 KHz roofing filter as there  
was an option to fit another 455 KHz filter which I suspect would have been used 
 for 16 KHz if the 20 KHz roofing filter was fitted.
 
My sets are in storage so can't confirm against CPU type or firmware but  
everything else seems to match.
Do you know where yours came from?
 
regards
