    You already have the lens mount (lens flange) attached to ubiquitous Thornton- Pickard curtain shutter! Diameters were pretty standard so you should be able to find a UK lens that fits.

  9. Re: What kind of lens is this Steinheil in Munchen?

    Steinheil has traditionally most data on the (lost?) flange.

    Re: Early Petzval stop location

    The central stop - or the position of the Waterhouse slot - was never quite in the middle. The “correct” position is dependent on the comparative focal lengths of the front and rear optical groups.
