An early brass petzval lens engraved. G&C M Registered Trade Mark. Very well built and heavy, this beautiful lens keeps its part of mistery. I guess it's a Peerless Quick Acting Portrait (designed by Morrisson for Scovill in USA) and distributed in Europe by Gasc & Charconnet, France. As petzval optical design, there is a front achromat of two cemented glasses, and rear achromat of two glasses separated by air.
The brass barrel is shiny, and get a waterhouse slot (no waterstop is included). There is also a rack & pinion focusing sliding system, but seems locked. I don't want overforce, and you'll use the camera bellows for focusing. The mounting flange is included.This petzval lens covers 5x7in at infinity with ease. Diameter at mounting thread: 80mm. External diameter of flange: 104mm. A beautiful portrait lens, very fast for amazing rendering in portraiture photography. Great tool for large format photographers and wet plate enthusiasts.
