2 Atlas Craftsman Southbend 10" 12" Lathe 8” & 4” 3 & 4 Jaw Chuck 1 1/2 X 8 TPI. The 4” chuck has no key- I’m not sure if it’s been modified- when you spin the knob on it all three jaws move at the same time. Does go in and out but sticks a bit from not being used in a long time. It’s marked AJUST TRU and is made by Buck, No 1443. Made in USA. The 8” chuck has a key (not original). and is marked 10-885-1 but has no makers name. It may be an original Craftsman Atlas but I�...��m not positive. It is an independent chuck. The 8” one is a nice chuck. These are in good used shape, show some normal usage wear. Comes as seen in photos. Free shipping to LOWER 48 STATES ONLY
