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,

makes sense. Thanks. Let's hear from all the LF gurus.
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...
Here is an image taken with my 15.5" Velostigmat with the defuser maxed out after removing the small screw. BTW the 11x14 Vitax lens has long ago been moved to a better home where one of the forum...
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,...
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. ...
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.
Thank you Mark. That is a very helpful description. It made my “light bulb” come on.
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.
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.
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...
even more pictures
I acquired this Darlot Pill Box a while ago and recently took it apart.
Looking to learn more about it. Any clue when it was made and your thoughts. I believe it is a 24" lens which has had its...
Louis, the thought crossed my mind too that it was an enlarger. Some google search did show this company did make enlargers too.
Does the lens look like one that would be used in the 1920-1930s in...
How was this item (see picture) used?
sorry about the direction of a couple of those pics.
here are some more.
This studio camera does not have a back, but i think the removable plate holder(?) is 10 x 10 i believe. Any idea how it would have been originally configured? it has 36" bellows and Taylor-Hobson...
Very old thread...but for those interested in having the instructions for the original DeGroff Shutter Booster.
Thank you Steven. I appreciate the benefit of your research. This one and my many Derory lens are some of my favorite.
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.
Have Lerebours et Secretan with FL 7 inches +/- with three lens all have matching sn 8941 as does the barrel. It also has the “washer” stop. it also has the metal lens cap. Any idea when this lens...
Recently have been able to attach my WP graflex Shutter with WP back to my V8. Looking forward to using it. Also have a Century WP camera with 3 WP glass plate holders with metal film inserts which I...
Here is the link I was thinking about......
Chris Perez did a great analysis of what this lens can do. He posted a link on this forum in 2006 IIRCC
Great lens. I have one I purchased from Kerry Thalman years ago. Need to use it more.
Very nice.
Old Roses #2. 8x10 contact print taken with Holmes, Booth & Hayden lens.
John & Dave, thanks. That's what I thought (remove negs from Printfile Proofer sleeve); had made a couple with 35mm neg proof sheets earlier in the day, but it was a pain to organize the strips and...
John & Dave, does the negative sleeve page cause any issues when you use the Printfile Proofer? Thanks, Jon
Old thread, but thought I would post a couple of images taken with my 9 inch Spencer Port-land lens and developed earlier this month in Ilfolsol 3 1+14. I apologize for the dusty scan, images from...
Good point. In an effort to process more film while working on my learning curve, I have brought AO home with 35mm & 120mm tanks. Plan to develop some bulk ISO 400 film. Will start between 5-7...
Resurrecting this thread and hope to bring it new life.
Does anyone have any additional developing suggestions for various films in a jobo? I just mixed up a liter of AO today and want to see what I...
Tried attaching a copy of the Durst CLS 2000 operating manual, but my pdf is too large. Probably not too different than the one Ic-racer provided. Send me a pm with your email and I can email the...
yes, it has the phone cord connection. i think i need to get the male LPL 3 contact plug and splice it.
That appears to be best. Thanks Jon.

I have a 4x5 Saunders LPL enlarger which has a foot switch which can be used with its timer. Does anyone know of an adapter or plug I can get to make them work as one? Some other option? See...
Jobo did make a plastic sheet with rivot buttons to hold the 11x14 film in place in their 3062 and 3063 drums (think these are the right numbers) I found one years ago and it works well. There was a...
The aperture scale may be the US System scale. However, the chart I saw starts with f2 which would be f6.6
I appreciate everyone's insights, recommendations, and observations. I typically have used a grain focuser, but thought I would try it with a red filter while fine tuning image on the photo paper. ...
My 4x5 LPL enlarger does not have the red filter unit. I can buy one, but ouch on the price. Any suggestions on using a red camera lens filter with a swing mechanism so it can be used to fine tune...
Even if the "golden window" is a small window, you have the timing down.
