Ilex /shutter/Kodak lens I.D.

Dear List:

I wonder if one of the more learned and erudite members of this knowledgeable list could identify an Ilex No. 4 ACME shutter, with a Kodak Ektar 7.5 inch focal length, with a maximum aperture of f:4.5, and a minimum aperture of f:32 ? Facetiousness aside, the serial numbers are listed below:

Lens serial number : EI 512
Shutter serial number: S22-55

There is another number on the Ilex, in much tinier lettering, which I assume is a patent number,.
However: 2,249,548; there are also some faded numbers which might be a patent number, but I can't read them.

I use the lens in my 10x8 Folmer Graflex Century Universal, serial number 16174; would any one no its approximate age?

There are two other lenses I generally use, both stunning: A Rodenstock Sironar f:6.8 360mm, and a Schneider Symmar, f5.6 360mm. These have given me my best results so far with 10x8 Ziatypes.

Thanks,
