Nice score Brent.
I have sold my Metric SM1340. So I no longer have direct access to the lathe. It may be possible to get the new owner to help you out with measurements and detailed pictures of the thread dial.
I think I do have some pictures.
I still have an electronic copy of the manual; it has the blueprint of the threading dial. No dimensions are given, it is isometric, but they give enough fastener info to reverse engineer it - if required.
