The 1.5-3.0 mHz PTO unit from a T-195 or T-368 would work.  I use a modified 
T-368 PTO/exciter unit as an all- band VFO unit.  With the bare PTO, you 
will need to mechanically mount it in something and provide a power supply.  
Just be careful not to run the unit all way to the end of the tuning range.  
With any of the Collins-type PTO's, if you run it all way to the end, far 
enough to feel mechanical resistance at the shaft, you have already 
permanently damaged the internal tuning mechanism.
