French made petzval lens in excellent condition.  Believed to be their 120mm f3.6 model however the front glass measures 60mm across and the rear even bigger so it may be faster than f3.6.  (We measured it around f2.5 using the TTL meter on an S2 leica)  Minor marks but overall clean and haze free glass and certainly very usable.  Flange included.  No waterhouse stops included.
