Rodenstock Sironar-N 210/5.6 MC, Copal 1, caps. Used maybe twice. LN-, the - being the fact that it was mounted on a lens board at one time. An all-purpose "long" standard lens for 4x5" format view cameras or a standard lens for 5x7" cameras. $360, return privilege, I pay FedEx shipping in US. Jim jim@brick.org
