For Trade FT/FS (US): Tominon 280mm f/4.5 Lens from Copier

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.

You could make an infinity target with this thing.
You need
1) lens
2)light tight tube
3)Target that has a transparent section to it.. Developed neg with an "X" scratched into it or similar.
Then assemble the three pieces onto the tube. measuring from the neg to optical ctr of lens. Use a small lamp
behind it for illumitination
