Biggest indicator I've seen

Interesting. Not actually a big indicator, certainly a large dial. I'd like to know brand name. 10mm travel and .oo1 or .01 increments? I'm guessing .001 from here. That would raise resolution far easier than building an all new 'clock'. The real test will be determining repeatability.
Compared to a test indicator, [most will not accept a longer tip], where an increases hand [balanced] is not causing a ratio change. The original body probably was 10mm travel. Generally speaking, fine increment travel indicators aren't prevalent. They were; used with setting mics on precision machinery, before digital readouts. Dollar for dollar,I still like them better.

Closest common equivalent is Starrett Last Word 711-D-10, a test indicator. Very sensitive, therefore tedious to set up, used when it literally will be the last word. Another fine increment test unit on hand is .000050 [50 millionths] Brown & Sharpe, is used a little more often for less than standard increments on boring head; by halving any reading.
Of yours, I cannot guess the intended use; but atop column of a boring mill for small incremental adjustments [not moves of serious travel] would serve nicely. Large moves could be set, if touched off on Jo-blocks start and finish. That allows backlash correction, monitored by indicator.
