    Re: The Perils of BRASSO (and similar)

    The lens is a Joseph Levy, London who existed for about a decade and eventually joined up with the Houghton/Butcher consolidation - like Zeiss-Ikon similar in Germany in 1926.

    GDR (DDR) or somewhere else in the old Soviet influence block where there were plenty of scrap cameras from the early 20th Century and very little to buy in shops!

    The Perils of BRASSO (and similar)

    I am sure this brass polishing substance has many dear names around world - but this the version I know best from household use.

    This is not about the evils of cleaning off character-giving patina...
  4. Re: Thornton Pickard Imperial restoration project

    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.

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

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

    After his co-discovery of the Aplanat/RR with Dallmeyer (1866?), Steinheil developed a lot of similar lenses which had rather thick...

    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.

    Re: First year Heliar's

    I think Jim's was the 30cm focal length and Voigtlander wrote it up as being for the 16x21cm format in 1907. This is the original Heliar optical design - not the Dynar redesign. It is, however,...

    Doesn't look much like an Imagon to me unless the front "lens" is a plain glass/filter?

    Perhaps Rodenstock transferred the "Acquired trade name" to grace the Imagon product?

  27. Re: A bit stuck (literally) on how to proceed taking apart this Liesegang Lens

    This lens is nearer a "Globe" lens than a RR version and the fixed maximum aperture looks nearer F.20 than the usual F.14.
