Years ago, I used to bid on eBay auctions of lenses that I suspected would wind up in a landfill if I didn't bid. They were usually unwanted because they lacked apertures, but since I could mount them into shutters, I didn't find that too great an impediment. Here's one of the "rescued".
This is a 12 inch f/6.3 Dallmeyer Perfac. The Vade Mecum identifies it as a Tessar design, along with the Serrac and Dalmac series. It indicates a 6 in lens will cover 4x5. I popped this on the V8 'dorff and it covered 8x10 easily.
As you can see from the photos, the iris was removed and a great, gaping slash was hacksawed into the barrel to allow waterhouse stops to be used. Ugly, but not necessarily detrimental. Use a really thick waterhouse stop.
The real problem with this lens is that it's got some clouding between the cemented rear elements. It's noticable, but the lens is still quite capable of taking good photos. It's not overwhelming, but it's just enough to have some impact on contrast. I'd take the rear element out and recement it, but our overeager friend with the hacksaw cut a slash across the lip of the rear element, apparently to use a tool to remove the rear cell from the barrel. In doing so, he's munged the threads by which the rear elements would be extracted from the cell. Twenty minutes of careful grinding with a Dremel would probably cure that situation, but I have better things to do.
Problems? Yes. Usable? Yes. Comes with a flange and mounted on a Masonite 4x4 lensboard.
The orphan is yours for $65 + shipping. Paypal accepted. Satisfaction guaranteed.
One last thing: this is one honkin' chunk of brass. Not even 2 1/2" in diameter, it weighs almost 2 lbs. The barrel has way more brass than necessary.
