Jacobs 50 Collet Chuck: Which Collets?

[Splat]

So I might have a line on a Jacobs series/model 50 collet chuck for my Heavy 10L. Does anyone know what collets (#'s or series) this chuck takes? Thank you.

50 series? or 500 series?

does it look like this?


if so 500 series rubber flex collets will work.

they sell on ebay for 95-150 ish,

Yea, the 900 series collets will not work in a 50 series collet chuck.

For reference:
The 500 series collets will hold up to about 1.060"
The 900 series collets will hold up to about 1.375"

Also the 500 series collets are shaped a little different on the nose of them, from the 900 series collets.

No, the one I'm considering looks like this one:


I've since found out that the series 500 collets should work with the series 50 collet chuck. I don't think they make new ones anymore, or are there another brand that will fit?
