An antique french lens engraved. DETHEUX - BULARD, 3 et 5 rue du Marche des Blancs Manteaux PARIS, Magasin de Photographie, Brevete SGDG. A very early and rare french petzval lens, Detheux-Bulard starts its photographic activity in 1850.
This petzval lens is with waterhouse slot, I already owned a Dutheux-Bulard lens with washer stop from 1852. So I guess this one for sale was made between 1860/1870. The brass barrel wears signs of age, with lot of varnish loss. Rack & pinion focusing system works with a little help.
Glasses are complete, front achromat is well cemented, and rear achromat get separating ring between flint and crown lens. I can't unscrew front achromat from the barrel. And of course, there is some dust and slight marks.
These are two small chips on the very edge of rear element (see attached picture with red arrows). Original mounting flange is included and has a dent (sse attached picture) but is usable.
Diameter at mounting thread: 95mm. External diameter of flange: 135.A beautiful historical piece of French photography, of 150 years old, in esthetic used condition, not restored, but most important thing: glasses are in working condition. I'm pretty sure this nice tool is ready to take amazing pictures for large format wet plate enthusiasts. Check my other antique lenses for sale.
