I have a few nice pieces I got from a guy many years ago, but most of yours look brand new!!
He had told me he had a box of tools for sale, some wrenches, a couple of hammers, various small sockets, Allen wrenches, punches, some one inch drive ratchet and sockets stuff (big stuff, of which I had none).
We met up and he had quit his job a few days before and was getting out of machining. He threw all his measuring gauges into the box, several dividers, calipers, micrometers of various sizes, dial indicators and a few of the more delicate instruments were Starrett but there were also some Mikuni and Stanley. The most valuable thing he tossed in though was a huge assortment of triangle carbide cutting tips for milling.
I had agreed to pay forty bucks for his little six drawer cabinet with "a few tools" in it, but he said for fifty, I could have the whole thing.
Done and done.
