In the early 1970s, acquired my first 8x10 lens from Burk & James, a very early 12 inch f/4.5 Wollensak Velostigmat. Burke & James had (re?)coated the optics and mounted it in a Betax No 5 shutter along with one of their 8x10 Commercial view cameras. Back then I received a hand typed personal letter from B&J documenting the history of the lens!

Amazing Greg! That kind of service is long gone. I wonder if Lynn Jones may have had something to do with that...

I've got a 5x8 version (8.5", I guess), #214900, and it's uncoated, so the several mentioned before that with coating must have been among the first coated ones, or coated later.

Interesting Michael. This lens seem to have been well maintained so perhaps someone had did have it coated somewhere along the way...and turned out to be much newer than I thought it would be. I guess I just lucked out for once...Thank you!

Mine shows the tiniest bit of separation around the edges, completely insignificant, which is a common problem with these lenses. I don't find it hard to think that in the 50s and 60s it would have been economical to tear them down to be recemented, and coating them at that time because you could and you were there would have been completely logical.
