Re: New Resource for Wollensak Lenses and Shutters
Thank you, Dan, for the suggestion. I’ve supplemented the Alphax and Betax Compendium descriptions with a link to the detailed dimensional information.
Good question about whether the small Deltax and Gammax shutters share thread dimensions with the same-sized Alphax and Betax shutters. I don’t have technical drawings for Gammax/Deltax, but maybe I can find some lens cells to try swapping around.

Sorry, Randy, Wollensak's process and enlarging lenses are a separate, even more abstruse subject and are out of the scope of the Compendium, which focuses on still camera lenses and shutters.
Re: New Resource for Wollensak Lenses and Shutters
Good menu based site to quickly see some old catalogs. Thanks. I believe there were shorter Verito's than 5" though. Mark Sawyer would know.
Re: New Resource for Wollensak Lenses and Shutters
I haven’t found documentation of a Verito shorter than 5”, but if any one has such a reference, I would be happy to incorporate it.
Re: New Resource for Wollensak Lenses and Shutters
This is great. This helped me date a barrel lens in a Packard shutter that came with my V8 Deardorff. Based on the camera and the lens 1941 to 45. Such beautiful stuff
Thanks.

On page 134 of The Cinema Handbook, (Austin Celestin Lescarboura, 1921), there's a reference to "Verito lenses of 2-inch and 3-inch focus":

Mind you, the MP Verito (MP for Motion Picture) had a periscopic design:

Very noticeable when used in old movies.
The women are always SF and the men sharp.
Re: New Resource for Wollensak Lenses and Shutters
Randy,
I have a 210 mm f6.8 Graphic Raptar Wide Field lens I bought from Dagor 77 at least 10 years ago. He had a number of them he was selling on eBay. They were late production lenses Dagor 77 acquired after the factory closed. I had mine mounted in an Alphax shutter for use on both my 4X5 and 8X10 cameras. Mine has an image circle of about 15 inches, so it does work as my "wide-angle" on the 8X10. I was told it is a Reverse Dagor design. I find the lens to be compact and very sharp. I would assume your longer version is an up-sized model with the same positive characteristics.
I hope this answers at least some of your questions. I certainly am not a technical expert.
