Dennis,
Might it be a film that has a base with texture that 'allows' for
retouching on
the 'back' like some of the Kodak 'professional' films?

Dennis,
That's quite 'normal' for nearly any film processed in a pyro/
staining developer.
I can just about guarantee that you will not see what you are
observing to have a
deleterious effect when enlarged to a print. It is NOT similar to
the obvious 'clumping'
that one will normally see with reticulation of the emulsion due
to temperature 'shock'.
Just as a Carbon print can 'show' extremely fine physical relief
from an oblique angle, a
pyrogallol or pyrocatechin developer will produce a similar
'physical effect' on the film
emulsion due to 'hardening' of the gelatin by the tanning.

Yes I am aware of the relief of the image and the emulsion looks
great on this film, the problem is on the base.
