I've been tasked to make ready a Internet Sale (more in a later post) found this item,. Obviously a shutter timer ! Who made it? Haven't been
able to make it quite work though! 16 is probably seconds ! The Silver knob can be turned, I guess to thread in to the cable release. I think
you thread tight then wind the whole apparatus. By then pushing the same knob you release the timer and run to join the others in the
photo. When threaded I was fearful of stripping the threads and I wasn't able to "wind-it" . There is "spring" resistance when holding in the
hand, but not able to simulate a "timed" response. It simply springs back to the original position no geared "zzzzz" response etc. I did
notice though the button does seem to have a light in-out spring too. Could be broken I guess! Any ideas!

Chuck, More likely a frame counter from a 6x6 camera (usually 12 frames) which has been fitted with an adapter to allow 16 frames (1 5\8" x 2 1\4") I have such an adapter for my Rolleiflex T but my counter is built in and changes to 16 frames automatically when I fit the adapter in place. Educated guess. Not definitive. Best, LM.

Frame counter from a 4.5x6 (on 120 film) camera. I have a similar rig on my Welta Perfekta. The silver thingy in the middle moves to engage the counter at the start of a roll; you advance the film using the red window in the back of the camera til the first frame, then engage the counter to count off the remaining frames. At the end of the roll it springs back to '0'. Well that's how mine works, yours' could have a slightly different function. Not sure of the camera.

It looks like part of the 16-on adaptor kit for the Rolleicord ("Germany").

Wow.. is this not really the best BEST forum on the net!?!?! Me with 16 seconds ... DUUHH ?? of course!! It just didn't occur to me. And yes indeed it is with a Rolleiflex 6x6. Which I realized had a timer for the shutter! And as Len mentioned; it is with a Rolleiflex T . It has both a a 4x4 mask and a 4x5,5 so I assume the insert is for 4x4. Also 16 frames per roll. I think a 6x4,5 is certainly a more useful combo than 4x4 / 127! Is the 4x5,5 the so called super slide?
the masks

It's definitely a 16 exp. kit for a Rollei. I have one for a Rolleicord Va: you simply remove the 12 exposure frame counter from the camera by loosening the chrome bolt, and install the 16 exp. counter. Then you install the rectangular film gate attachment inside the camera. I never did learn how to use the apparent masks with the "ears" or tabs. I bought a Mamiya film punch that punches out 4X4 chips from the 16 exp. frames, and mounted them as super-slides. Some Kodak Ektagraphic projectors project the superslides without vignetting, and they are pretty impressive. The mounts are increasingly hard to find today.

The 4x4, not the 4x5.5, is the Superslide. Small enough to fit in 35 mm format projectors, bigger than the regular 35 mm format slides. Hence the name.

Ok... then what is this mask 4x5,5? Will this frame counter give the proper separation for 4x4 and there's another one specifically for 6x4,5 or does it just count 16?

Chuck,
The "mask" on the left side your photo that has a 4X5.5 opening is clipped into the square film gate inside the camera, and it reduces the frame down to the size needed to get 16 exposures on a 120 film. To make Superslides you take those frames and clip or punch out a 40X40mm chip and mount it in a Superslide mount - which has the same outside dimensions as a 35mm slide. The kit I have also came with brown colored plastic masks that I think were meant to rest on the viewfinder screen for composing to the cropped dimensions. Those masks did not fit my Rolleicord Va, so when I had the camera cla'd I had a Maxwell screen with the Superslide crop lines on it installed. When you project the slides they completely fill a square screen, and since you are using the central part of the lens, mostly, the resolution can be excellent.
