[HAM] What model is it?

[Dave Bishop]

If it really has a tremulant drawbar on the upper right side, then its not a 
CV.  If it has a tremulant drawbar and a church style cabinet, it would be a 
D (which is a BC in a church style cabinet).  Some Ds were upgraded in the 
field to have an aftermarket vibrato\chorus system added.  The only "add-on" 
I've seen was turning an A into an AV, and in that setup the C/V switch was 
in front of your left knee while the knob was on the upper left.  I suspect 
a different kit was offered to install the C/V switch in the same place as 
it is on a CV.  So I'm guessing that it is a DV.  If it is, there should be 
a small white sticker by the model plate certifying the conversion.  It will 
also have sharp key edges.  In any event, it should be a fine instrument.
