The vise on the 500A milling attachment is either home-made of after-market. However, as nearly as I can tell from the photos, it was made to fit the existing pintle on the 10-501 main upright casting. So no harm done. If you were to locate the original 10-502 part, it should still fit. However, the home-made part appears to be a functional equivalent and aside from weighing more, should work about the same. I have the instruction sheets on the 500A if you don't. Can't recall whether they are in Downloads or not. If not, I can certainly upload them.
On the gear question, I don't know the answer. But it is possible that the cast iron (your description) ones may be the original design and the die case ones the second design. The 9" originally came out with Change Gears with part numbers of the form "9-101-(tooth count)". Early in 10" and 12" production these all became suffix "A". So it is possible that the cast iron ones are the original design and the Zamack ones the first revision.

Also, in the middle of your photo that includes the Steady Rest are some gears that look like they are part of the power cross-feed. Perhaps they are new parts that never got installed?
