I have this big lens that I still haven't done anything with so I probably won't get to it especially since I don't think my Speed will focus it. Has a couple marks in the front glass and some internal dust. I'd like to trade for a faster projector lens that would cover 6x7 or ideally, 4x5. A Grafmatic would be excellent, or 4x5 film holders, or 4x5 film or 120 film or bulk 46mm or 127 or a beat up Hassy prism that I could adapt to a Rollei or a battery pack/motor drive for an F1 New or a Speed Finder for an F1 New or an AA pack for GX680 or front cosmetic panel for Minolta Autocord non-metered model or a Rolleifix or Rollei Pano Head. Or $60 plus shipping, which will be considerable given this thing's size and weight. Please PM if interested.
