We have a (I think) Donaldson Stereo Separator spare. It's a black tube with an angled lens at the front that moves.

Is this worth anything to anyone?

 

Cheers,

I am 100% sure you have a Allen Stereo Separator, these would only fit on the Zeiss FF1 - FF4 fundus cameras. Am not sure about FF1 have never really seen one but in pictures. The lens on the front would rotate left or right when the foot pedal was pushed to obtain a picture. Plus it came with a switch so you could manually move the optics from one side to the other.

These were expensive back in the 70's and I could do better stereo's during angiography and slides by hand movement.

Lisa, that is exactly what you have an "Allen Stereo Seperator". We have two of these at the clinic. Tried using it many years ago but found it too restrictive for my liking.

As to the value? Your guess is probably as good as anyone's. You might see if one of the third party service reps/resellers has any interest.

Let us know how you make out.

Good luck,
