I’m relic hunting in an old mining camp that I think is from the early 1900s. I’ve found mining tags and other equipment but came across this today. I think it’s the face of a timer of some sort but not sure. It has “turn past five then set time” stamped at the top. There’s a 0 at top center, a 5 with 14 hash marks at the top right, then 10 at lower right, 15 in lower center, 20 at lower left, 14 hash marks up to 25 at top left. Any ideas of what this went to and how old it is? Thanks.

All I can think of is a dial from a 25 minute mechanical timer.
