Carl Zeiss Jena eyepiece set (3) Homal f=70, 37.5, 20 27mm Near mint condition except there is a small nick on the f=70 top lens. Nothing that would interfere with it's use but it's there.
They are 658 362 Homal II f=-70, 574 168 Homal VI f=-37.5 and 622 853 Homal IV f=-20. Tube size is 27mm.
I think these are projection lenses but I am not sure. It is a beautiful set!
I am not certain what they were made for. Perhaps even a telescope? I added the "Best Offer" option. You tell me what they are worth to you, and please also tell me what you think (Or know) they were used for.
Check out my old Meteorite Times articles called Micro Visions. (I no longer write this). Here is a link to a back issue list (with live links) of my articles. There is some beautiful art in those micrographs and some useful information (I hope!).

Also, my son is setting up a Gallery and art sales site of my micrographs. Please check it out http://www.tomphillipsmicro.com/ I am currently setting up my meteorite micrograph gallery within this site. My old gallery has been down for some time, keep checking it out as it is an ongoing project.
Please look at my other auctions. I will always combine shipping costs. Just email me if you win more than one auction.
