Beautiful 90mm Sinar select 90mm lens with 221mm coverage. Huge coverage for 4x5. Glass is great.
Currently in a Sinar DB board, but fits a Copal 0. I do have a mint condition Black Copal 0 if you're interested. Has f8, not f6.8 scale, but I have scans of the correct scale to print/stick. Just ask.
On the Sinar board, asking $250. $350 in the Copal.
