That certainly is one of the prettiest I've ever seen too. I don't know of any factory stops with that kind of attention to detail and finish.
About the only thing I might have done differently in design would be that I would make the thread a 40 pitch and leave a straight, clean ring of the major diameter of the adjusting nut to allow inscribing .001" graduations. That would make it a micrometer carriage stop.
What pitch thread does it have now? Looks like it might be about a 20TPI. If that's the case the adjusting nut seems big enough that you could turn a short (1/8"?) wide diameter just below the depth of the grooves, make a press-fit aluminum ring and inscribe 50 graduations around it.
Just a thought.
