    Re: Tough removal of brass lens

    Thank you for your great responses. I tried the "Q-tip with lighter fluid" on the threads of my old Leclair Petzval and it worked wonderfully.
    Best to all,

    Tough removal of brass lens

    The brass lens cells on my old petzval are difficult to thread and unthread on and off the brass barrel. The threads are not crossed. What is recommended to help smooth the screwing on and off...

    Re: post "in Galli style"

  5. Re: Dating 24" Darlot Pill Box and your thoughts about it

    here are more and hopefully clearer pictures of the lens edge. The "Darlot" is light in pencil on the edge. Next to Darlot is "Paris". Then a symbol or initials, not sure what, maybe some Steve,...
  6. Re: Dating 24" Darlot Pill Box and your thoughts about it

    Yes Steve, you hit the nail on the head....the lid is soldered on and there isn't any trace of a thread. It must have started as part of a large petzval or cobbled by someone who had various parts. ...
  7. Re: Dating 24" Darlot Pill Box and your thoughts about it

    I truly appreciate the benefits of your knowledge. I know the edge of the lens has “Darlot” penciled. I will take a closer look this weekend and post better pictures of the lens edge.
  8. Re: Dating 24" Darlot Pill Box and your thoughts about it

    Thank you Mark. That is a very helpful description. It made my “light bulb” come on.
  9. Re: Dating 24" Darlot Pill Box and your thoughts about it

    If the FL is measured from the Waterhouse slot to the image on the wall it would be 28 inches and 23 inches from rear of lens.
  10. Re: Dating 24" Darlot Pill Box and your thoughts about it

    I agree it is a professional cobble. I may not have calculated its FL correctly. Need to get it on lensboard and try it out. Attached more pics for analysis....I appreciate everyone's input.
  11. Re: Dating 24" Darlot Pill Box and your thoughts about it

    Hi Steve,
    The lens is approximately 93.472 mm or 3.68 inches in diameter. The waterhouse slot has a "pocket" or "sleeve" the for the aperture stop to be held in place. So could use a post-it paper...

  15. Re: Any thoughts on how to make Sichel Studio Camera usable?

    went back and reviewed the earlier posts and it appears my lens was made after 1855, but before 1860 since it uses the "washer" system.
