I'm pretty sure they were - these were on the units by 1950.

D&H also, when it inherited those units.  Didn't the GM&O also have
those?

No, the Erie/EL units were the small boxes. I thought that large number
boards were produced concurrently, and were determined by the road.

Yes, pretty early...
