anyone familiar with ACMI Borescopes?
 

My cousin gave me one today. Model B-53-A lamp 31.

I ran it into my 30-06 barrel, and its amazing.

A Google search yielded squat. Anyone know value? Age?

Don't know value or age but I do know that A.C.M.I stands for "American Cystoscope Makers Intl." they are used predominantly in the medical field. They are now owned by Gyrus ACMI an Olympus company. Maybe that will help your search.

The link is what eBay has.
