I understood you very well (I sat about 6 years with my good friend 
Michael from Portsmouth in our office - practising  best british humor... ;-)  )

So the next step I will do, open my next TB, but I think it is time now to 
verify these boxes by real comparative measurements. 
Unfortunately I do have no characterized OCXO for reference. 
But there are many Thunderbolts around already, and there are many 
hi Q references around as well...
