Hello --

I recently purchased an auction lot of camera odds and ends, and one of the items in the lot was this strange contraption. I have no idea what it is, but it looks like some kind of accessory for later Filmo models. Can anyone identify it?

This thing has a periscope like viewfinder that runs down the middle of the item, and on either side are mounts for what look like removable lens accessories -- they might be diopters. On the back is an odd rotating piece with a clamp like holder.

Here is the front of the item:

And this is the rear of the item:

If you need any more info on this item in order to identify it please ask. I'm really interested to find out what this thing is, especially since it has a viewfinder on it.

Thanks for your help,

Aaron

I've never seen one before. Can you give us a dimension reference, like the diameter of one of the openings? My only guess is that it might be lab equipment, part of a printer?

The diameter of the opening is about 2.5cm. Hope that helps.

someone sold me a similar unit and said it was a close-up adaptor. I have not figured out how to begin using it.

Patented 1942

Wonder how much ol' Alton Morton made off that one...

I bet that actually is 25.4mm/1in! Does it have a thread? If so, it might well be a C mount...

Cheers, Dave

Thanks for all the info. I never would have guessed this was an accessory for a Double Run 8 camera. Very interesting.
