What does "X" mean?

Howard
 

Hi everyone,
I have a question concerning the codes of the serial numbers on SB lathes. The list of explanations for the codes are pretty straight forward.  But for the "X" all it says is "Special". 
I was curious if anyone knows what the encompasses? What makes "Special" special? 
I was just curious.
Thanks,

My X is a 1hp 3 phase two speed motor.

A lot of times, depending on age, it’s a
 Hardened bed

Just bought a 1964 16” x 6ft South Bend lathe. It is serial number 11667HKX15 and has a 2-3/8-6 threaded spindle nose, I suspect that makes it an “X” in the South Bend’s factory parlance.

According to the SB Form 7324 "Tooling Dimensions”
2-3/4-6 was standard for the 16” lathe.

1943 SB catalog lists 2-3/8-6, buyer told me it is 2-3/8-6, it has a 9” 3-jaw on it right now. I will take the chuck off and see what It actually is.

I should have said “seller” told me it’s a 2-3/8-6 spindle nose. Having one heck of a time getting the chuck off, not budging.

I too thought my X was the hardened bed, but my 13 Inch, s_n 6715TKX13, CLC145B, 6-25-1958, serial number card says "CAM LOCK, TOGGLE CLUTCH APRON, HARD. BED, SCREWS, T.S. SPINDLE".

Maybe it is all these items. It has a taper attachment, but the unit code for that is noted on the back of the sheet.

The first generation 16" was introduced in July of 1912. The spindle was 2-3/8-8, nose length was 2".
That spindle ended in June of 1922, they reduced the nose length to 1-3/4.
In December of 1924 they change the spindle threads to 2-3/8-6, and changed the shoulder size to 2-15/16.
In December of 1926 they changed the Taper Diameter to 1.567
In December of 1939 the changed the Taper Diameter to 1.6295 and the shoulder to 2-7/8
These are the only 5 changes I know of, for the 16" threaded spindle, all were .602 taper
