Part #135 confusion gone. It is part of the dial mechanism. Google "found this":
See https://worldradiohistory.com/Archive-Ri...hanges.pdf (page 13 of file):

It will be noticed in the schematic
on page 7-31, 7-32 of Rider's Volume
VII, that two parts carry the same
number: No. 135.  One is the pilot
light and this is the correct number for
this part; the 'second is a switch, lo-
cated on the schematic just below and
to the left of the 6J5G AVC tube.
The number of this switch should be
137.  This number does not appear in
the list of parts on page 7-36, but the
switch is used on the automatic dial
mechanism and appears in the parts
list under "Code 122" as "Plunger
Stop and Switch Assembly, Part No.
45-2330."

I thought something wasn't right about that.
Now something else to check. Hopefully something easier to access.
