A puzzle for you engineers (What is this??)

The Turkish Delight
Like a variable speed transmission or gearbox. The large round dish with the teeth are different ratios and the rotating ring moves along that shaft to turn it at different ratios depending on where it is vs the diameter of the dish.
Am I right?

What ever it is is looks like it cost a lot of money and time to make.
Further look and the side gear is a spiral so fully adjustable. May be part of a WWII bomb site?

Bombsight was on the right track huh?
In that case it could be used to compute barrel elevation-vs-distance used for large artillery peices... Howitzers and the like. That would kind of make sense if it wound up and then wound back down.

Interesting new photos. 
Come on PoLaK - you sadist - give us some more clues! :D
Age? Civil or military? Run at slow or fast speeds? Used for part of one disk cycle at a time, or a full cycle, or a continuous stream of cycles alternating from one side to another....
Any hints at all, please?

A guess..
Could it be part of a device for cranking engines (perhaps aero engines) - starting with a lower speed (higher torque) crank, and building up to a fast spin??
Chocks away chaps... :p
OK, I'm clutching at straws here...

I'll say it's part of an alt-azimuth control for a radio telescop.
(I'm clutching too

Another straw clutch..
A device for putting 'spin' on bombs before dropping them. I seem to remember that some bombs (dropped to bounce on water and then blow up dams for instance) were spun before dropping them, to help achieve a particular trajectory.

In fact, a couple of days ago I was talking to a friend of mine and he told me that another of his friends had been involved in exactly that - the design of the various shapes and angles of such fins, to achieve various outcomes for different bombing applications. However, the bombs I was thinking about were designed to bounce on top of the water (like skipping stones across a pond) and then sink to the base of the dam wall before exploding. If I remember rightly, they didn't have fins (which would have interfered with the bouncing across the water).
Of course we could be on the wrong track. Maybe it's just the drive mechanism for an early prototype personal vibrator..

another guess
Going from the bombsight clue... what if it is part of a device to help calculate the lead angle for old anti-aircraft artillery? Perhaps the two wheels are for the X and Y axes. There would have to be other devices for input on speed and altitude... but those disks may do the angle. If the altitute was a constant (above gound distance of the airplane), then the lead amount would have to increase at an increasing rate given the angle of the gun to the ground... and speed would probably be factored in linearly.
I'm not so great at math, so thats just a gut feeling sorta thing... I'd love to know what it really is, the suspense is killing me!

Does it look like it would fit in this setup?

How about a film (or chart recorder paper) advance device with integral drive for the supply and take-up spools? Those spools need to change the rate of rotation in opposition to one another (the supply roll speeds up as the take-up spool slows down)while the film (or chart paper) advance must remain constant. The picture in the link looks like drum recorders, but inspired my guess.
