11/45 bulbs determined

The 11/45 uses OL-2 also? Then it's easy! :-)
The 8/M uses the exact same OL-2 too., but they're unobtanium now, but
an [1]almost perfect replacement is the (as you've deduced) CM7371
which is current production.

I bought a batch from Mouser, which retails at $0.90/bulb IIRC.

[1] the legs are narrower than the OL2 so it'll be a bit loose in the
socket. If it's directly soldered on the PCB then it's not an issue.
