Review on Graduation Interval measuring: An Exclusive Indicator by Robert Ryokan

Seems to be quite well made. Maybe not well thought out, I can't say. There isn't a good way to mount it to the base of the indicator, I wanted it to point straight at the end of the indicator arm and figured the brass adapter would do the trick, but it wouldn't tip over and flop and fall when I put it let it. I would only be 100% sure it would fit your setup, but if you have a normal indicator base it won't work, at least it won't work like any other normal indicator I've used.
