Hi All,

I recently acquired one of these guys and am having trouble finding much information on it. I see Gundlach has changed hands a good bit throughout its history (Gundlach Manufacturing Corp., Manhattan Optical, Rochester Lens, Wollensak...). The seller says it was manufactured in 1922 and is a petzval type design. The lens is marked that it will indeed cover 8x10.

I'm just curious to learn about the focal length and any other details since it's not easily searchable. Any help or advice on resources to learn more would be greatly appreciated! I'm attaching some photos of the lens and an advert the seller included.



All the Best,

Cate
