    I thought endoscope probes were a lot smaller than that.

    Not in the early days they were.

    No, seriously. The rectigraph will be hard to identify if it's not described inside the book it's lying on, the LVM. I'll put in my $0.02 and throw a small searching party.

    Have you seen this link before?

    Scoville

    The Rectipgraph gets mentioned there as a Lancaster type lens, manufactured around the period you mentioned. Perhaps this is a lead?

    And you must have found out yourself as well that the Rectigraph company made early photocopiers - but a lot later than 1895.

    yes ,I forgot to mention that its a Gundlach lens,but I dont think its the rapid rectigraph(convertible),Ive got an old Grundlach catalogue from 1915 ,and its not directly mentioned in that ,it may just be a version of the TR symmetrical anastigmat .
