My grandfather was a machinist tool and die maker.
No idea on the date of this picture, they retired the machine when he retired in the mid 80's
They got a new computerize lathe to replace his, he said when they can pass him up, he will retire (they wanted him to learn to use the new one).
It took a few years for them to do that with the learning curve and equipment issues. View attachment 1715418498
Well, boring those deep holes isn't exactly what most CNC lathes were meant for. Not unless they got a customized one. That actually looks like a huge gun drill (or?) to me. Definitely not a regular lathe, for sure.
