Help with Leblond lathe chuck change

I have a 19" swing leblond, I would like to put a smaller self centering size on. From what I see it looks like it's just on with a collar. Is there one I can use, (without spending lots).

Not enough info !! Sounds like you have a"L' style spindle with the collar. But even with a Chinese new chuck depending on size and mount most likely $300 up.
Outside of the collar is 5.250 infront of it, which is what comes off the backside of the face is 4.125.

After opening the picture click on it again to enlarge. Yes looks like you have a "L-0" spindle. Your current chuck has a integral back plate,so if you get a "flat back " chuck you will also need a back plate.

The collar has right hand threads.

That means if you are in front of the lathe, the spanner will go UP and AWAY from you in the process of loosening - since you are unscrewing it from the back of the chuck
