I have a document for a similar lathe, but I see that it doesn't match
mine exactly. One option in those pages shows MT 5 for the spindle. My
measurements seem to agree with MT 5 pretty close, so I think it is
correct.

To be sure, I guess I should buy an MT 5 center and try it.

I did that when I had a bigger lathe. I believe I still have a No. 5 lathe
center, NOS NIB. Email me offline if you're interested in it -- to email me, see
