Fujinon Info Source?

It seems that info regarding Fujinon enlarging lenses is extremely hard to find (at least the models I'm tracking down). I'm sorting through some things that came with a recent purchase and I can't find a trail of info for a few things.

There were some Fujinon EFC-II lenses included. They have odd markings such as 1:6/64.5 ƒ5.6 on one that has only 5.6, 8 and 11 for f stop settings. Another is a 35mm ƒ5.6. Also, there are some extremely large-sized Fujinons mounted in large flared mounts with 3 bolt hole flanges. For instance, the 135 ƒ5.6 is 3-4 times the size of a 135 Rodagon and dwarfs it when sitting side by side. Are these possibly from a large Fuji processor? They are beautifully made and look very expensive.

I think I'll run some tests on some of these optics and see if there happens to be any jewels mixed in there.

I don't know any of the stuff you mentioned above, but here's my advice:

I happen to use a lot of Fuji products including the enlarging equipment because of the region/market I'm in, but that doesn't mean there's a lot of information about them, either. So, when I have specific questions, I call the customer service of Fuji in Japan directly, which has been often more helpful than searching online.

Have you contacted the one in your region/market?
