I agree Robert.  I have maybe a dozen or more Racal receivers here, all 
the UK ones had Racal made frequency standards.  Most of the US built 
ones had bought in ovens, notably the 6790/GM.  The 6772Es came with a 
nice looking US Racal badged on the outside TCXO all of which however 
seem now to be faulty, even the NOS spare one I had.  Opening them up 
you find inside a nasty looking plastic OEM module they must have 
seriously  regretted buying :^)
