I'm looking at a lathe, a South Bend 9x32. I haven't gone to see it in person yet; the seller estimates it is from "the 40s", no model information on it, but here is a picture:

When I asked the seller if it came with the change gears, he replied that it "... comes with complete gearing - it's not quick change."
However, that looks a lot like the first lathe on this page, which appears to require change gears:

So does this one require change gears, or is there a transmission in there somewhere to change the speed for turning and/or threading?
Also, myself knowing little about lathes, what desirable features would a simple lathe like this not have (besides power cross feed, which seller stated it didn't have)?
I read what you wrote to mean that the seller has and will give you all the change gears that the lathe needs. The transmission on a Model A is the curved box with two levers and an instruction plate mounted over the left-end base, the place where the drum switch is mounted in the photo of the Model C.
This has the threading chart for the Model B and C.

text lists the gear set sizes.
The "stud gear" is on the outer end of the stud that holds the swinging plate which selects forward, reverse or off. The "screw gear" is the gear attached to the end of the leadscrew. When the chart shows 18 and 72 tooth gears on the same pivot they are attached together and rotate at the same speed, making a 4:1 reduction.
That was why I asked him, but my read on his response was that he doesn't believe it needs them. My homework made me think it does need change gears, and I thank you for verifying that for me.
I would ask him again, but electronic communication seems to be very difficult with him, so I might have to go and see it in person.
I did notice some change gears on Ebay; a quick look gives me that idea that they seem to be about $100 for a set.
Thanks Jim, I appreciate it. Just out of curiosity, how much would you expect to pay for something like this, assuming it isn't too terribly worn, but without any change gears? (assuming I'm not an Iggy or Gunner) :)
When the seller said "comes with gearing, is not quick change" that means change gears - A box or rack of gears that you need to change - ie, take a wrench, remove this gear, add that gear, get this feed or thread. There's usually a chart to tell you which gears to use where.
Quick change involve gears that you can "quickly change" between by using a lever system. No box or rack of separate gears. No wrench.
As for changing the speed of the headstock, you move the flat belt to different pulleys. Has nothing to do with the gearing, other than the back gears.
You might want to drop $12 or so on "How to Run a Lathe" (perhaps cheaper if you can find a copy that doesn't need to be shipped to you).

So long as the work fits and you are not trying to run production, you can get a lot done on a 9" - but you might yearn for power cross feed. However, not having it will make you learn to turn the dials smoothly. Depends on how much facing you'll be doing, and how much you'll mind having to hand-feed.
I don't see any on the local Craigslist for the past few months, and the second-hand machinery dealer I visited this afternoon has no metal lathes, so I don't know the current market.
This appears to be a loose change gear lathe, you MUST get a stack of 8 or 9 gears as part of the tooling that comes with the lathe.
I'm not a SB lathe user, not sure if this comes with babbit or ball bearing headstock, looks like a babbit set up, someone else will need to chime in. A ball bearing headstock will have the spindle sticking out of a 4" or so diameter casting, a babbit version will be half that.
A worn babbit setup for a newbie is disaster. Nothing but grief. You should be able to put a pry bar under the chuck and lift up, get no more than .001" or so. Any more and either pass on it or plan on learning how to repair things.
Around here a Logan or SB setup > Jim Wilk>> I read what you wrote to mean that the seller has and will give you
Cool, thanks Roy. If I go look at it, maybe I should bring my mag base and indicator to see how much the chuck wiggles around. I'll try to figure out the difference between babbiit and bearings.
This one in particular, the fellow is asking $650. I don't know how much of that is what he expects it to be worth, and how much of that is wiggle room. He did say it doesn't look like it has been used much (I don't think he has used it much, if at all, himself), but I've heard that song before....
I guessed $700 for the asking price and considered writing a range of $200 to $1200. I only see what's on the tags, not what the buyers actually paid.
What's the condition of the 3 and 4 jaw chucks? New chucks cost me nearly as much as the lathe and the steady rest was another $100. Does it have a tool post?
I picked up a lathe from work (brand not important)that had been used in the weld shop to turn parts for weld fixtures. Babbit head, about .020" play. Piece of trash, sold it as soon as I could. Later bought a mid
40's Logan 200 for $300 replaced the headstock bearing, new 3 jaw chuck, Chinese quick change post, a decent drill chuck for the tail stock, and a nice collection of tool bits for another $300 or so. It's not as heavy duty as the big ones at work but it's really nice to do a quick part or two late at night.
Thanks Roy. I looked at some pictures last night, and if I am correct, the babbitt type has a top held on by two screws, like the way a crankshaft is held in it's journal. I'll look for that.
It more than likely comes with the 'lantern' style tool post with a left, right, and straight holder. It's a start but you would really like a quick change:
