Stevens wheel

I’m slowly but surely collecting things for this year’s Alcan 5000. I found this Stevens Rally Indicator on eBay for $27 shipped. It’s basically a circular slide rule for calculating distances and times. It’s pretty nifty, and most importantly, lets me — someone unable to manually calculate things quickly under duress — have an easy, visually simple way to calculate splits. Now I just need to find timepieces that wouldn’t look out of place in a 60’s rally car, and figure out what I’m going to do for a rally odometer.
