the ortho are 0.965: diameter- prob not worth big $
the mzw might be a Lichtenknecker, google it
the clave eyepieces can be worth something in very good condition, they are more of a collectors piece, as far as viewing with them imo they are nothing special, a true plossl type eyepiece, some users in europe or US might be inclined to pay decent money for them 150-250
