The lens in is extremely good shape including it's original set of waterhouse stops.
Matching serial numbers on lens and stops. Lens was made back in 1891.
So far a nice find but it was holding a great simple lens cap alternative.
As most of us are using these lenses and mostly petzval lenses wide open we never use the
What about using the waterhouse slot to close the lens???
In the leather case holder the water house stops there was also a thin black piece of plastic.
Est voila, you just don't need a lens cap anymore!
Why haven't thought about that idea before. So all credits go to it's previous owner, Henk Peters.
