Signals van generators

[Rod Salter]

Hi all
Still here
Long time nothing much done
Did COVID, cough sleep, cough, sleep, and sleep
Had worse colds

Still collecting some of the small missing pieces

I got this generator,
Is it for a signals van?

Also information, photos, links required
Of the pto driven generator for the signals van
Believe it is a Delco Remy
What size?
Where/how was it mounted?
Belt driven?

Thanks, rod
