[Boatanchors] Sig gen I-151

[WA5CAB at cs.com]

Larry,

If the "I-151" is on a removable plate, it's possible it is a Depot plate.  
They often had much less information on them than did the original plate, 
including sometimes omission of the model letter.  I just looked at a photo 
of I-151-A in the manual I have and it has I think a different type of tuning 
dial from what you described.  However, the tube complement is the same.
