The model 260 OXCOs are definitely double-oven oscillators.
I suppose that it's possible that some OXCO variations might not have the 
EFC function, but I find that quite unusual, since there is no other means 
to adjust the frequency of the oscillator (notable exceptions being the HP 
10811 and 10544 models). The MTI 260 model, being a very high quality OXCO, 
surely needs some means to adjust the frequency.
Is the EFC pin on the units that you have?  If it is present, it's possible 
that the units that you have are defective.
