What Are These Fuji Optics?

Recently retired and finally sifting through stored items... I stumbled into a box with these Fuji lenses. They are:

35mm ƒ5.6
49.9mm ƒ5.6
64.5mm ƒ6.0
75mm ƒ4.5
105mm ƒ5.6

They appear to be EFC and EFCII by their markings. I believe they are part of a pro lab's equipment that I bought out some years back and were mingled in with a large box of premium enlarging lenses (30+!). Are they part of some duplicating equipment and flat field? Coverage? Source for information? Thanks in advance!

Enlarging lenses.

They may have been installed in commercial printing equipment.
