I'm looking for a rear (back) rail for my shaggy old Kodak 2D.
Without more bellows draw, it's hard to evaluate my 500mm wollaston lenses.
Condition is not important, I'm real handy with c-clamps, glue, and air nailers...
A 2D with the original bellows will hardly draw 500mm. I had trouble with 450mm.
You will *also* want one of those extension boxes on the lens board mount or rear extender for the film plane.
