This is the classic and rare Post WWII version of this lens which is Coated.
These are almost never seen, and when you do see them, they're beat to pieces because if a pro was lucky enough to have one, it got USED!
This one is in lovely shape, and the shutter works excellent. All 3 scales are there for you.
When both groups are present this is the finest 312mm lens ever designed for LF and ULF. Yes, without the front lens shade in place (they're normally missing and most folks have never even seen one) it covers 11X14 with movements. With just the rear group, you have 19" component (as Ansel used to say,) and if you put the front group in the rear behind the shutter alone you have 26 1/2" lens.
The individual groups used alone are sensational! Ansel made 30X40 enlargements from his 8X10 negs made with individual components of this lens. $1830.00 Talk to me.
