Coated Wollensak Anastigmat Extreme Wide Angle 6.25" (159mm) f/12.5
I purchased this from Kerry Thallman on the LFForum (where this lens is also listed for sale) and since 8x10 is a studio-only situation for me now it's time to sell off this wonderful field lens. The lens comes with a brass flange which can be screwed into your board or as a retaining ring (how I used it). This is the cleanest copy I've ever seen and I believe Kerry had advertised it as being New,Old Stock when I bought it from him.
Haven't tested the shutter speeds, but I shot them as marked on the Rapax shutter and never had any complaints about the exposures. This lens has a wonderful roundness to the tones I prefer in my work compared to the clinical bite of modern, computer designed glass (if I can get a little biased here). If there was any chance I was going to shoot 8x10 in the field in the future you would be prying this out of cold, dead fingers.
