Its metric. I bought it off Ebay a while back because the price was
right, but I can't find the descriptive number anywhere now. I would
like to get some more the same size, but longer for an application, but
for the
life of me I can't recall the screw number to look for. Its 6mm
diameter
and the pitch is about 1mm.

After much search I am beginning to think this is a fairly rare size ball
screw.
Yikes, looks like it is a very fine pitch. Well, the only thing that
matters is the diameter and pitch. Your 6x1 makes me think
6 mm dia and 1 mm pitch. I have actually seen some like
that listed on eBay, so you ought to just search there and
see what comes up. The real problem is they are rarely made very
long as whip and stiffness become problems.

The seller on this one said it was C3, but after measuring its travel a
couple times it can't be any better than C7. Probably closer to C9. THK
does make one but, "Perforated poop masked crusader!!!" those things are
expensive. I think I'll just keep an open search on Ebay and see if any pop
up. In the mean time I think I'll explore other options for this
application. Wish I had room for 16mm. There are tons of those out there
at a reasonable price.
