Might some of the many ICs available these days be useful in restoring 
some of this old equipment.  Unless one wanted to be a purist in the 
restoration.  Perhaps a switching power supply circuit could be combined 
with a gel cell or a few D cells to replace the 67.5 V battery.

Another problem with equipment this old is bandwidth.  These radios are 
from the era of 15kHz deviation and 60 kHz channel spacing.   It might 
be nice to have a channel devoted to wide band operation.  Maybe it 
would have to just be on 6M to find enough space.

I don't have anything this old anymore.  Just a few PT-300s and some 
Motracs.

Some nice pictures.  You've got a picture of my first VHF-FM mobile 
radio on there, the last one on the page.  Actually, it was a later 
version and went up to 52.525, an FMTR-50D - 50 watts from a pair of 
807s, loctal tubes, a vibrator supply for the receiver and a dynamotor 
for the transmitter.   Don't leave it on unless the engine is running to 
keep the battery charged.
