old antique lab measure stirrer rod, steampunk vintage scientific laboratory equipment, metal stir stick

Tarnished plated brass metal stirrer with ball tip, marked with numbers as shown (presumably calibrated for measuring). It looks like silver plate or maybe tin over the brass?

The rod is slightly bent up from use or years of storage. Has no makers marks that I could find. I think this would look great as a drinks stirrer after a good cleaning and polishing. So weirdly cool, and gives your cocktails that mad doctor vibe!
