Sometimes getting information about a camera is pretty piecemeal.
Sources & mentions in the video:
Label & strut pictures. And quite a collection:
1905 Montgomery Ward catalog:
Wollensak Junior info & 1903 catalog:
1912-1913 Wollensak Lens and Shutter Catalog:
Aperture, f-Stops, and the U.S. System:
Camera video with images is here.
The camera was working on bulb (B) most of the time but not instant (I). The lens was in dire need of cleaning too.
This isn’t a complete tear-down. I didn’t open the viewfinder or remove the wind knob. This started just as notes for myself so there are some gaps in the images. I’ll try to fill in with text instructions.
Not shown: 1) Cleaned the shutter parts. I used cotton swabs and lighter fluid. 2) Re-blackened the aperture with a permanent marker. 3) Cleaned the lens front and back with lens cleaner. I doubt if it is coated so window cleaner might be OK.
1/240 frames per second = 0.004166666666667 seconds per frame (~4.2ms).
Open for 4 frames = shutter open for 0.016666666666667 (~16.7ms).
Turn it into a nice shutter speed style fraction: 1/X = 0.0167. X = 60.
If I’d been thinking, since 240 is a multiple of 60 and 4 and the shutter was open for 4 frames, I could have just done it in my head. Duh.
In my defense, I do this for a lot of old, slow shutters and it’s rarely this clean.
A tear-down post is here.
Not much to show that’s not in the video. If I get crazy and try again, I’ll post more here.
Update: I used some little snips from film & loaded a couple of single frames. What do you even call the piece of film that comes out of the canister but doesn’t quite reach the shutter frame? Any way, the opposite end from the leader.
