This is one of my engineers toys! The ubiquitous 9X20 Lathe though it lives in an outside workshop so keeping the rust at bay is a full time job. I have had this lathe for some twenty years and is the most accurate and it still works for a living but not as hard.
I do wish I did live on your side of the water because I am sure there is a good paying hobby for some retired entrepreneurial engineer and gun user, just turning out firing pins to order out of the correct material that should last more than a couple of years. Though I do know how hard it can be to be to extract the cash for your work!!!
