I knew a guy who worked for Kodak decoding spy stuff.

An old friend of mine, that I first met in 1973 was a MI dealer, primarily of used gear. When I met Barry, he was working out of his parents garage, but eventually had a couple of different storefronts over the decades. He had a veritable treasure trove of vintage, and otherwise, MI gear of every kind, even some stereo equipment. But, all the really good stuff that one would want to buy usually had a sign on it:
NOT FOR SALE
When he died in the mid '00s, everything was in a warehouse somewhere, and I have no idea what became of it all. He had a decent size room (probably around 15" x 15") in the back of his last store with every wall covered up to the ceiling in Kustom T&R amps and cabs. In other parts of the store, I remember he had some McIntosh stereo gear, an Earthwood ABG (which I'd played every so often, over the years), a Gibson Style U, along with lots of other gear, vintage and more "recent acquisitions". I bought my first new Rickenbacker from Barry, a MG 4001, in the mid '70s, and a 1966 Fender BandMaster head in the late '90s. His late brother, Cory, ran the store for awhile, while Barry was
living in the bar around the corner from the shop; I bought my first Alembic from Cory in the early '90s.
The only thing I ever sold to Barry was my Western Electric 639B, something I regret to this day (the only MI related gear I really feel that way about); I tried to buy it back from him a few years later but he had no recollection of it (one of his alcholism related problems, unfortunately).
