As you can see from the picture, this is an original Orthostar (made by Nikon, I believe) offered by Tom Cave in the 60s. This particular one is coming from a Cave employee of the 60s who I've finally convinced to clean out his old eyepiece box! The optics on this one look perfect, the barrel has a few marks on it, there is a scratch that runs around the outside top barrel much of the way that has been touched up to avoid oxidation. You should be able to see it in the photo.
We don't know what this is worth, so we're taking offers. Thanks for looking. Fred
