In Martin Burwash's "Vis Major" (see my review: [www.rypn.org]) he speaks of a self jacking mechanism on the GN rotaries in 1910. I believe the steam actuated jacking was used to raise the body so that the rotary could be pulled back when stalled out with lots of snow underneath. Martin assures me that they really did have this feature.

Do OM and OY have self jacking?
