Anyone familiar with the optical device for measuring distance that is similar to a dual telescope. You look at an object and adjust the device to bring the 2 images together. The distance to the object is then indicarted. Some may just indicate the angle. The one's I've seen were about 12 inches wide and 1 or 2 deep. Google only showed laser this & laser that; advertizers only apparantly. Any ideas on where such devices might be sold or what a suitable search term would be.

They are a bit out of fashion these days. Try Surplus Shack or similar. Keyword you want are optical range finder.
"Rangefinder".

Thanks Martin - I'll give Surplus Shack a look and try again with Google and Yahoo.

Thanks Phil, I'll see how that works.

I used to have a 1950's Leica with the "split image rangefinder". I think that's the search term you need to use.

coincidence rangefinder, I've never seen one that small.
There is the odd ex WWII one that comes up on eBay from time to time. I have no idea if they are in good working condition but some look plausible (if a little overpriced for what they are). eg.
Laser rangefinders are all the rage now.
Clifford - I'll that term a try. Do you rember if that Leica displayed the range found or just used it for it's own purposes?

There were two little lenses about 5cm apart, and a viewfinder that combined the two images, presumably with a half-silvered mirror. One of the view lenses was visible through a mirror steered by a mechanical linkage to the focus lever. The linkage had the correct geometry to track the focal distance.

Clifford - was the focus lever marked with the focal distance?

Martin - I took a look at the ebay pages. There was a "Watameter shoe mount rangefinder" that I bought. A bit of a gamble but that's part of ebay. I do appreciate your suggestions for these were the first found on the internet.

The focal distance was on the base of the lens tube, the way it usually is on manual-focus lenses. The lever was a knob on the side of that, adjacent the body.

Thanks, that clarifies the nature of the device.
