Calling all know-it alls - What is this?

I came across an interesting item at a car-boot sale (garage sale for those friends across the pond) this weekend and the seller didn't know what it was.

IIRC (spelling aside) it had written on it - M10 Correctielschiff (not sure about the spelling)

It was a white plastic board with a large dial in the center. Along the right edge of the board there was a scale in centimeters & along the top edge there was a scale in inches.

Under the dial there was (what I assumed) a range scale going upto 3500m & the dial itself was divided into 32 parts in what looked like centimeters again. The first quarter of the dial had a reversed scale on it too.

Does anyone know what it is?

And should I have bought both of them for £2.50?
