Upon scanning both sets of negatives the scans seem so similar
at the same settings that I think your assement is correct.

However there is one last issue in my mind the surface imperfections
of the Forte, it shows alot of white scratches and pits. All I did was
thread the reel so I doubt they were my fault.

Any added thoughts on this
