Tell me please if this gizmo is a rangefinder?

[tomperson]

Hi all,
I recently found this gizmo at a local auction website:

Could it be a rangefinder for using with those cameras that don't have one? (Such as zone focus cameras)

It seems pretty old, i don't know if that may affect its performance?

How much would be reasonable to pay for it? They are selling it at 20 dollars.

Thanks!

Yes, that looks like a shoe mount rangefinder.

The only rangefinders I've seen were for the first (rangefinderless) Leica, or huge ones as used for artillery spotting and battleships 😉

But this sure looks like one!

Yep...I believe that's a "clip on" RF. I believe there's one similar to it on Ritzcam's website under "accessories".
