4 Zeiss Abbe type 1 eyepieces

This is a near complete set of the coveted original Zeiss Abbe eyepieces.  These are very rare and only rarely come up for sale.  This includes the 25mm, 16mm, 6mm, and 4mm.  The only one missing from the set is the 10mm.  They are all in very good to excellent condition.  The glass is also in excellent condition in all 4 of them as well.   The 4mm does have a slight blemish in the "4" on the print as seen in the pic.  Also included is a generic case in excellent condition.
