The only difference is how they attach to the carriage. But it is a big difference and the heavy 10 one is usually cheaper.

I tried the 80/16 a little to fast, changing the 80 to a 56 or even a 40 would that get me some where's in between ?

Hi Oscar.
I have a 1934 Cat #405. Its similar to your lathe but not as heavy or good.
Here is what I do.
I manually feed most all of my work. (I also have a Heavy 10 and do the same)
If I am looking for a very good finish on a long piece than I use the slow power feed.
 
To answer your question
80/56*0.00225=0.00321 Not a lot faster.
If you want an intermediate feed, just remove the 4:1 compound. Let the 80 tooth idler drive the 80 T  screw gear form the 16 tooth stud gear.
This will give you about a 0.009” per turn feed.

Jim you were write i fire my 9" the first time and the feed is really slow if i was to buy one gear like change the 80 on the lead screw to a 56 how much more feed would that give me? My gear chart is entirely different than another member with a model 407. I believe you said now i was .002- .00225 feed rate

Check your number again.

If it is 14627 TKX,  then it was shipped between 

April 1975 and July 1975

Using Google image search I found South Bend model 4229 serial #5 sold for around $1200, bit of a rusty one but would clean up, serial #80 went for $340 and was a real rust bucket. They were manufactured in 1988.

Both sold on government liquidation auction.

As it sits.
 
16/80 = 0.2 (Where 16 is your stud gear and 80 is the screw gear.
This is further reduced by the compound  ¼*0.2= 0.05.
(The 80 tooth the engages with the stud gear does not contribute to any gear reduction but does reverse the lead screw rotation)
That means that for every turn of the spindle (The stud gear rotates at the same RPM as the spindle) the screw gear rotates 0.05 turns.
Now, I believe you have an 8 TPI lead screw.
One turn of the lead screw moves the saddle 0.125”.
If there were nothing else going one, then for every turn of the spindle the saddle would move 0.05 * 0.125” =  0.00625”
 
But if you have an apron with both cross and horizontal feed, there is a further (approximate) 3:1 reduction.
 
Thus your slow feed would be 0.00625/3 = 0.0021” per turn of the spindle.
 
As a note if you mount the compound on the upper rail of the banjo I believe it would engage the stud gear directly, eliminating the 80 tooth idler and an additional source of backlash but the rotation of the lead screw would be reversed.

yes mine is 16 pitch and the 80 is on the lead screw

I would appraise the complete deal as worth $1500 to $2000, if the ways are in good usable shape.
The 'new' SB 13 is a bit harder. Parts availbility would scare me off, for that price. I'd probably be looking for a LeBlond Servo Shift 15 or a SB Turnado (or variant). In some respects I think the price is justified as to compare to the offerings from Grizzly, JET etc.

No, I saw it. OK, the taper attachment is worth the price. The Steady rest and telescopic following rest, the buyer can sent to me for apprasal fees.
