Robert:
I have tried to answer your question as accurately as I can using D&RGW documentation instead of my personal opion. As often happens here, a few have to get personal and sarcastic.
I am currently researching and writing a two volume history of D&RGW/RGS snow fighting operations and equipment. When that is done, I will be working with two or three others to do one or two volumes on D&RGW and RGS MOW. I always try to share info with the group, but if it gets nasty again, you will have to wait for the books.
