I would like to trade my 60mm Unitron Kellner for a set of Unitron .965" eyepices Could also use a Unitron Diagonal. The eyepiece is for the super unihex. The barrel is threaded brass. There are some touched up nicks and dings on the black rings. The good news is the optics are in superb condition. I am not the original owner but I believe it to be a early vintage.
