That machine looks very old and somewhat abused. I can't believe it's never been used, maybe by the person selling it. but it's got to be 60 or more years old, You'd be buying a can of worms at best. No lead screw, and probably near impossible to buy one. Why is the lead screw mising, was it crashed. The first question I'd ask is how much can you afford, and what d you really want to achieve? Do you have any idea of the kind of things you want to make and or repair? After that I generally say buy the biggest and best you have room for and can afford. I see you are living in Frankston, I assume Frankston Vic. if so, there a quite a few machine tool selling companies with good showrooms in Melbourne, they usually also sell second hand machines that have been traded in. Buying from them may cost a little more but you've got a better chance of buying something that actually works. Good luck. Bob.
