Here is another request for help with a Darlot lens I recently purchased on E-Bay.
Here is the info found on the lens:
14 rCHAPON PARIS
The edge of one of the front elements is marked with Darlot + the address and a date of 1863. There are lots of initials on various parts of the lens body. The ring arround the rear element is with "D. PAYSAGE.
There is also a geared mechanism that moves the center of this lens. There appears to a place for another lens which is not there.
The lens is fairly large and has a brass cone. I estimate that the front element is about 77mm the rear about 65mm. The lens is about about 5" long but can be expanded by about 2-3" (pulled out to seperate the distance between the front and rear elements) when loosening a knob. I checked and it does cover 8x10.
My questions are the following. Is it a landscape lens? Is there a glass element missing from the center of the lens? (I payed good money for this lens and want to ake sure that it is complete) What is the lens design? Based on the Serial Number the body of the lens appears to be older than the date of 1863 edged into the front element. The lens body appears that this lens may be convertible??
I am becoming really interested in old lenses and any input is appreciated.
