Does anyone know where I can obtain 3 of these tubes?
I have tried the web with no result.
Any help will be greatly appreciated.

Try:
1. Antique Electronics Supply in Phoenix, AZ
2. Triode Electronics in Chicago
3. ESRC in Florida


I can't even find a datasheet on the thing... but it looks like a
pentode designed for a battery-powered radio.... 1.5V filament, 90V plate.

I am thinking a 1LD5 or 1LC5 might be a reasonable sub, with a base
adaptor.

I think it might be one of them furrin tubes from before the
standardized letter/number numbering system.

Maybe, but I found a bunch of circuits using it out there, like this one:
http://frank.pocnet.net/short/001/1/1SA6.gif which shows an IF stage.

This gives you basing and pinout, some nominal operating voltages, and you
can make a rough guess about transconductance.
