[Collins] Bristol Spline Tool

[Dr. Gerald N. Johnson, electrical engineer]

My research to date shows:

The S-line is said to require four Bristol spline sizes all 6 flute:
.060, .076, .096, and .111.

The 75A is said to require the three larger ones for the S-line.

Rooting through a 51J-3/R-388 I find the four used are 6 flute .111,
.096, and .060 and 4 flute .069.

So to replenish the wrench holder in this receiver I can buy the
individual angle wrenches for less than a buck each while I'm ordering
other needed tools for other projects not found in Iowa captivity.

The reach of the Xcelite 99 series is very handy, and the short L
wrenches probably won't reach places like the dial bushing without a lot
of radio disassembly, maybe not even then.
