It's kinda against my religion to sell a lens that I've never even looked through on a GG, but hey! there's only so much time, and these guys' turn hasn't come around in years and the next decade don't look so good for them neither. You give 'em a try. I don't think any of them are dogs - just not interesting enough to me.
(1) 5 1/2" f/4.5 Ilex Paragon Anastigmat. These Ilex's get no respect, but are frequent recipients of nice comments for sharpness. Glass is good. Aperture moves OK - just a tiny bit stiff. No flange. No, I don't know what it's coverage is. Take your chances......$25 + shipping.
(2) 6 1/2" f/6.8 Goerz Tenastigmat. If it's Goerz, it's great, right? You tell me. VM indicates it's a dialyte that covers 4x6. Glass has lots of cleaning marks, but that doesn't bother smart ol' photogs like you, does it? Shutter is inoperable, but the aperture moves OK. $30 + shipping.
and the gem of the collection:
(3) 5x7 f/8 Seneca Rapid Rectilinear. At least we know what format it covers. Glass is nice, but the shutter is dead. Aperture works quite well. This one comes with a mounting flange, so I'm going to gouge you out of $40 + shipping.
