Wetmounting the negatives while scanning is worth a try. Use the 
least valuable for a first attempt. I can't guarantee that it 
doesn't harm them but where is the historic value, in the 
negative or in the image ?

I have maybe a thousand 35 mm B&W negatives, FP4, HP4 and Tri-X 
that are from 1968 - 1982 and none show that crazing, what has 
been the cause of it ?  I wasn't very careful either since then.
