Gauge

DDW's January Challenge Day 21 : Cracked

I spent the morning zooming around to see a couple of customers and sort out work over the next few days, which meant I was back in time to accompany the furry idiots and HV for the afternoon walk.
I knew what my blip would be, having seen this instrument panel a little while ago. I like the rusty colours and the unreadable gauge. Any guesses what it is on? (HV, you aren't allowed to guess, because you were there :P)
