What is the significant difference between using an 85B and an Orange (G) filter for B&W film. (TTL metering will take care of the difference in filter factor density number.)
tool around here

and check out the transmission curves.
One difference is in the cut off
Monochromatic orange filters are blocking blue and green, while 85B is attenuating them by about two stops.

I think Sevo answered it.
To me, orange is largely red with 50% green and has no blue component. The 85B has blue.
I have tried an 85B with Tri-X. Not much good at all.
