In November I acquired a steam 'tractor' that used to run at the Sycamore Illinois show. It looks custom built. It has a 20" diameter Orr & Sembower boiler built in 1925. The engine is a 3 x 3 E. H. Wachs with a 1/2" Gardner governor. Paul Woodworth, the Gardner expert found the records for the governor and said it was shipped on 6-1-1923 to the E. H. Wachs Co. in Chicago by the CB&Q R R for $12.00. So, I'm pretty sure the governor is original. It also has a 1 1/4" single chime whistle and a 3/8" Penberthy injector. My hope is to bring it back to life. Step one is for the State to come inspect the boiler.
