This was the oldest working steam tractor I saw at the SteamUp. 'Steering was exactly like a soapbox derby racer with ropes (chains here) attached to either side of a front axle that pivots in the center. I imaging its so much work to light, warm-up/pressurize & maintain that mules would be easier.
Rudy, thank you. You're most kind.
I've made *alot* of metering/exposure errors and haven't worked out the finer difference in compensation between low indoor light (the train detail shots) and bright direct sun. The raw scan would indicate this one's pretty close at 2.5 stops over metered value. It was incident metered, as the tractor was in motion.
