I mounted it to a technika board (Had to grind off the ends of the mount screws on back) and covers 4x5 and 5x7...Vignettes about an inch on 8x10 but of course will cover at portrait distance
$85 plus $11 shipping CONUS only.
I included a couple lens caps that fit...
I never shot with it so don't know it's characteristics, but you've seen these here before.
Paypal is fine
NOTE: With or without the lensboard (if you don't need it)
Richard Rankin sent me this on this lens (I'm no lens aficionado):
"It would either be, most likely, a triplet design, or much less likely given the shape and size, it could be a petzval. An RR lens is symmetrical and the front and rear glass would be identical in all respects."
