Ilex Anastigmat Series "C"?

Bought an unidentified lens labelled: Ilex Anastigmat Series "C" f6.3 on eBay for a whopping $10. That includes shipping. It's in great shape, but I haven't yet had time to try to focus it to see what it's all about. If it forms an image circle larger than medium format, I'll be pleased with the $10 price. Photos attched. Any ideas on what this is? The board it's mounted on is about 2" square for reference.

Thanks!

If that lens board is 2" across, the lens itself is a little under 1" across. Multiply that by 6.3 and you find that it's likely to be a 6" lens or thereabouts. Could be a 5", or a 6½" though - I haven't measured anywhere near exactly.

I believe, but can not confirm at this moment, that you have a 6" enlarging lens. There is no basic reason not to use it on the camera as it may do an excellent job. I frequently use some of my old enlarging lenses as taking lenses just for the heck of it. Most are especially good for closeups.

Damn, I thought I had done a pretty thorough search of the web before asking this question.... Thanks for the info! I'm pretty happy with it for the price. I'll remeasure when I get home to confirm the focal length.

Thanks!
