That was my first thought, partly because it seems to happen on one make of film and not the other. That the clean film is Tri X would be consistent with Kodak's high manufacturing QC. In 50+ years of photography, I have experienced failures at one time or another with film, paper and photochemical products of every other manufacturer, but only one (Xtol) from Kodak. With no aspersions intended, I don't know the track record of Foma.

I don't think  you can entirely count out factory flaw in the film
coating.  Especialy if you can't find anything in the camera to cause
little scratches. the small black lines in the second image seem to go 
in the direction the film travels through the camera.  I don't see how
processing would cause that.

I have run three rolls of film through my newly acquired Rolleicord Va and 
all seem to have a problem as shown in the link below.

When I use Fomapan 200 (developed in Rodinal) I get a whole flock of short 
vertical lines on the print.  These are especially noticeable when the
print
is highly magnified. With Tri-X (developed in HC110) I get black specs 
which are you can see in the sky areas of the prints.
I suspect that both of these problems are caused by dust which falls on 
the
film from someplace inside of the camera since I have had similar problems 
with the black specs when using a folder like a Moskva.  In this case,
however, I do not see any obvious places inside of the camera which could 
be
sources for the dust.  The interior of the camera looks quite clean.

Any ideas where the dust, if that is what I am seeing, could be coming
from?

Thanks,
Peter Schauss
