His doesn't. It looks exactly like the other Type 12s with no tuning dial: just that big socket 
with the cover over it right in the center of the front panel.

Seems to me Fair Radio Sales did this some time ago. Probably don't have any left now 
though.

Well, I don't know about the VHF models, but I DO know that the capacitors in the 190 - 550 
kHz models and the BC band models are identical with those in the earlier receivers, except 
that the newer ones don't have the dial drive. It is a fairly simple matter to remove that big 
socket in front, remove the original tuning cap, install the older one, then add the dial.

Thanks, Robert.
