This is an Ex PMR, VHF "low" band radio, originally used in an AA patrol vehicle. When purchased it had a "D" type connector on the side for some kind of data link, and was AM. The radio was designed for AM or FM use, and was quite simple to modify. A few components needed to be changed in the receiver to achieve full sensitivity, and the TX section had to be re-aligned.
I modified this old Nolton Nova 242 radio for use on 4 meters FM,
where it performed very well. Too well, in fact for it wasn't designed
for long overs, and a transistor desoldered itself. The radio worked
fine after the device was put back in the board and a fan fitted. Later
however it developed an irritating fault where the receiver fell silent
after a period of transmitting, until a little percussive maintenance
was applied. This may be a faulty TX/RX relay.

The unit is crystalled for three frequencies: 70.450, 70.425 and 70.3625. The latter was deliberately chosen to be a bit obscure, as it was used for a net in the Ashford area, until the sad, and sudden death of Peter G7LNH, a good friend and advocate for the 4m band.
