What is this lens?

I'm trying to build a large format 8x10 or larger as a fun project.

It says it's an f/8 process lens, but it has no aperture. Would the aperture have been mounted on the lens board? If so, I can't figure out where they get the f/8 spec from, unless that's the actual aperture of the lens by itself. Perhaps I'm missing something.

It is a front cell. No barrel, no diaphragm, no rear cell. Run away, run away!

To give you some idea of what is missing, have a look at a listing for the 10 1/2 inch version: http://www.ebay.com/itm/Wollensak-P...D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
