A lot of the information from my three earlier posts on the C&S plows came from an entire Burlington Bulletin dedicated to the Q's plows. Hol Wagner was the major contributor. It was #38 and is still available from the Burlington Hist soc.
The Jull used on the Alpine rials was mounted on NG trucks. The pictures show the trucks are not SG trucks with the wheels shoved closer together like most of the Leslie plows. Don't know if these came from the builder or were provided in Colorado. It was shipped on its own SG trucks to Colorado. As the 1st jull built by Southwark (UP 065) is the only one I have ever seen on a 4 wheel front truck, I always imagined the second Jull was built with a 6 wheel front truck like all the others built by Rogers, and had the trucks replaced in Colorado for the trials. I'm on the road working so don't have my information with me but I think the truck switch is mentioned. The Alpine trials on the narrow gauge sure wasn't a fair competition for the Jull and sure led to poor production for the plow. I think the Leslie plow was a better design and was rightly the more successful plow. Interesting that both types of plows were designed by Orange Jull. The Leslie brothers redesigned the plow wheel and obtained the patents which made it successful. Probably stole the glory (and future money) from Jull but the original Jull wheel was not near as successful.
Speaking of Julls and rotaries!! I have pictures of all the 11 Julls except the Pennsylvania RR plow. Would really like to see that one if anyone knows of a pic of it. Missing only a couple of the 155 rotaries built. Really looking for pictures of the Northern Pacific rotary #5. Have exhausted all the known leads
Almost as many rotaries built in other countries.
