LARGE ROSS No 3 CABINET PETZVAL PORTRAIT LENS No 52796 W/ WATERHOUSE STOP
Item History & Price
* Ross London No 3 Cabinet.*
* A renowned Lens, dates to sometime during the second half of the 19th Century.*
* With one (No 3) Waterhouse Stop, *
** With a Beam of Light shone through the Lens from Back to Front onto a Sheet of White Paper...... at the point at which the light attains its sharpest / pin-point focus the measurement is approximately 215.0 mm, this being the distance between the ou...ter surface of the Rear Lens and the Paper itself, I hope that makes sense and / or helps in some way, this is performed without the Waterhouse Stop being in place.**
* Front Lens with some scratches / cleaning marks and a few very tiny anomalies, only a little internal dust, all as shown in the Photographs, no cracks or chips, no major scratches or serious damage.*
* The Rear Lens is very clean with no visible wear.*
No mold or fungus at all, no other internal issues.
** The Rear Element consists of two Lenses with an air gap between them, separated by a fixed Metal Spacer, as shown.**
** All Lenses seat firmly, no rattles or movement when shaken.**
* Threads shown disassembled are all in good order, they tighten smoothly and fully.*
** The Hood is more than "Hand-tight", no excess force was used, I left it in place as well as the Front Element which obviously I couldn't access with the Hood still in situ, nothing is crooked or amiss, its just not been separated for a long time.**
* The Rack & Pinion Focus Mechanism is missing, *
The Sleeve slides firmly and smoothly along the body.
