I've got one of those - it came with my little Index mill. Fortunately
BS9 collets are still pretty common.

I found this page on the web.

I know when I got the collet adapter the seller pulled out a catalog
with a page like this to measure the collets with it to find out which
one it was and he said it was the only reason he actually had that
catalog.

I think mine is a Z - its written on the nail box I brought the
collets and collet adapter home in. I haven't actually had time to
set the mill up yet.

About Collets".
Machinery's Handbook is good, as far as it goes, but it doesn't go
all that far.
You can glean a fair amount of info from the tool catalogs, but they
don't cover "everything" either.

I recently did a little research when an HSM'er got a US Machine Tool
vertical milling machine and I wanted to show him the collets that fit
the adapter he had. These machines had #9 B&S spindles.
The company sold collet adapters of the "Universal" type, (series OW, Y,
Z and ZZ) which don't show up in any catalog I had ever seen.

While poking around, I found this site, FYI:

Sure was helpful to me.
