My source was Bruce Mitchell who is now in a different group of Fuji Film USA (now in Florida). But he used to be in charge????? of I believe Professional Services in NJ. These were his comments that were supposed to be what has come down from Fuji, Japan. No Velvia 50 is made in Japan, not the US. You may be seeing a difference and it may exist, but this is what I was told as being correct.
