    I have been working for several years digitising the 19th.century Dallmeyer archive held by Brent Library.
    I found a number of lantern slides showing lens making in the late 19th.century.

    What I am looking for is an explanation of exactly is going on in each slide.

    www.samackenna.co.uk/wetplate/lanternslides/lantern_slides.html

    I would value any suggestions that might be made.

    Most of the slide are showing grinding or polishing of lenses 53, 54, 60, and 61; I'm guessing that slide 57 is forming the lens housing, and 62 is machining a lens housing; and 58 may be an assembly work station; guesting 55 is an inspection or cleaning. Your guessing on 59 is as good as mine of annealing.

    I have no clue what's going on but those are some really interesting images. Thanks for sharing.
