Ive just aquired a rectigraph lens 16" approx and f9 in a wollensak shutter
cant find much mention of this lens anywhere,its patent date of '95 ,
appears to be symmetrical--any ideas on design /coverage ,aperture and shutter damaged
No, seriously. The rectigraph will be hard to identify if it's not described inside the book it's lying on, the LVM. I'll put in my $0.02 and throw a small searching party.
yes ,I forgot to mention that its a Gundlach lens,but I dont think its the rapid rectigraph(convertible),Ive got an old Grundlach catalogue from 1915 ,and its not directly mentioned in that ,it may just be a version of the TR symmetrical anastigmat .
