Derogy Paris Petzval 190mm f6 (?) Large Format Brass Lens [EXC]

This is a beautiful brass lens from the late 1800's or early 1900's. We estimate that it is ~190mm f6. It covers 4x5 and 5x7 (with soft corners). It is a wonderful lens for large format portraiture that may rival the Aero-Ektar and Leitz Hektor.

It is in excellent condition with light wear and works perfectly. The glass is clean with no haze, fungus and very light cleaning marks for its age.

A front cap is included.
