[MRCA] Need Burned out R1051 Dial Lamps

[Nick England]

The AN/WRC-1 (R-1051 and T-827) was introduced to the fleet in 1963 (500cps
increments originally).

The AN/URC-35 (RT-618) wasn't introduced to the fleet until 1967 (and it
had 100cps tuning increments then).

So I think the RT-618 intro was delayed and incorporated feedback about the
early R-1051 lamps, tuning, etc .

This 1962 development report shows the RT-618 prototype with 1kc step
tuning and rear access lamps

The rear lamps were a holdover from the original SC-series design but I
have no idea why they thought that was a good idea!
