Jan:
I tend to agree with Chris through my own experience. I had a
similar situation with the Rollei SL66 due to uneven shutter working
during the exposure and it was the main reason I sent it for CLA last
year. Some shots started to show bands of different density and the
number of shots showing the problem were increasing, the pattern were
bands because we are talking about a focal plane shutter; the TLR has
a leaf central shutter and it could be the cause for the distinct
pattern, it could have to do with the shutter speed too. It looks like
the shutter leaves don't open and don't close using the same speed.
This is an opinion based on my experience, as I wrote above, but I
could be wrong for your case, I don't know.

PS: Nice shots BTW.
