What is it?

[stranding]

Ok this should be an easy one.

The base of a revolving office chair or saddle stool?

I'm out for the evening so, again, the challenge is open to any who would like to pick it up.
Richard?

What is this accessory used for? How is it attached to the camera? What is it called?

 

[scifan57]

Here's another photo.

 

[AdmiralAdama]

Is it a rangefinder accessory?

[scifan57]

Is it a rangefinder accessory?
AA

It's an accessory for a rangefinder camera but it has nothing to do with the range finding or viewing parts of the camera.

 

[AdmiralAdama]

Is is an attachment for a right angle viewfinder?

AA

 

[scifan57]

The viewfinder and rangefinder are at the top of the camera. This accessory is fastened to the opposite end of the camera.

I can't find any pictures of it, but given your description and the looks of the device, I'd say it's some kind of fast film advance mechanism. Probably very popular with journalists in the day.

Leitz SCNOO winder.
Production era - 1935-1940
It's a trigger operated rapid-winder for Leica IIIc

If correct the win should go to twerp for the break-thru. He knew what it was by looking at it.

Wow! Lots of pictures for it, once you have the right search terms.

I favore accuracy over guesswork, so as far as I'm concerned the Admiral won. Either way, I'm happy to go with SciFan's decision.

Sorry about the absence but you are right.It is the SCNOO winder.
This particular SCNOO is the earlier version that attached to IIIa and IIIb cameras,which had a slightly smaller body than the IIIc camera.The SCNOOs for the IIIc are significantly rarer and worth several thousand dollars to a collector.

Here is the SCNOO attached to the camera.
Since you've deferred to twerppoet,take it away,twerppoet.

Although the Admiral did supply the answer to the only remaining unanswered question,he has deferred to you,twerppoet. Show us the way to the next challenge.
