Months ago I was watching an episode of The Avengers. It had some nice old school scopes being used as props.
I had some time today, so I tracked it down on YouTube. The portion of footage that has the scope I would like starts at 40 seconds. Part 2 of 5.

Scattered through parts 1, 3, 4 and 5 are some other scopes as well. At least one of them was a mock up.
Diana Rigg (as Emma Peel) is alright too.
