Michael,

I am willing to accept what you say about the thickness and length of 620
compared to 120.  I just seem to remember reading and hearing that it was
slightly different especially in thickness and maybe length. Well, so much
for relying on memory. :-)  Happy to be corrected when wrong; but my
understanding as to differences in thickness would help explain curl - too
bad it evidently does not fit the facts.

120 and 620 film were the same size width, length and thickness. The only
difference was the shape of the spools. The 620 spool had a very thin core
and slim ends. The 120 spool had a thicker core and fatter ends. The 620
spool and film together made a  more compact package than a spool of 120. If
I remember correctly, there were problems with film curl with 620.  There
were very few high end camera that used 620. Hasselblad always used 120.
