Been in storage for years. 5 inch objective in cell. very short focal length f/5
maybe a former binocular objective or? excellent condition

EDIT: November 30th

I brought the lens to OPT (Oceanside photo and Telescope) yesterday for their opinion. They believe it?s a custom made machined lens cell, they also tested the objective lens with a televue eyepiece and there was no purple fringing and and was told it?s a high quality objective but no markings so the manufacturer is unknown.

EDIT: December 3rd
I unscrewed the cell retainer ring, removed the achromat lens and added 2 pictures.
