History: A very early portrait petzval for the 8x10 format. As with many early french lenses it doesnt feature an engraving on the outer barrel, but both, the front and one of the rear elements are marked with lead on the glass with 'Bourquin'.

Bourquin was among the very first opticians who made photographic equipment in the early 1840ies!  He is also well known for his Dragon box camera which is also featured in the George Eastman Museum:

Condition: the lens is in very nice and authentic condition. The brass of the lens comes with an authentic and warm patina, showing only minimal wear. The rack & pinion is comple and working. The lens was made before the waterhouse era, so it doesnt feature a waterhouse slot. The glass is in quite good condition, it shows only very light cleaning marks, but overall it is very clear and doesnt show any signs of seperation or damage.

This lens has about 300mm focal lenght (12") and an open aperture of F3.8. It will cover 5x7 and 8x10 format with a nice petzval character especially at portrait distance.

Lens comes with a fitting flange and the original brass lenscap.
