Nice collection. That Hardinge is a great lathe, but it is not not the cherished HLVH. It also looks like a threaded spindle. Mine is a decent lathe (Smart & Brown) that looks similar, but it also has a threaded spindle. That's a real disadvantage when using a chuck (rather than collet as that one has). It is quite a hairy ordeal to machine in reverse, which is what I am trying to compensate for with my threads on the Mitutoyo DRO. He had a lot of tooling, and that can be more important. Some people neglect that aspect.
I am not really a hoarder, but I am a keeper. I still have and use some tools I got 70 years ago while in elementary school. All of my big stuff dates from the mid-1970's. I do love tools.
