Well, I have never paid much attention to the C&S rotaries for no reason in particular. I trust that the tenders are from SG locomotives? I did not realize how much they are similar to D&RG(W) OM and OY, particularly the blades. Big surprise as all four machines were built under the Leslie Patent. Does anyone have the builders numbers for the C&S machines? How close are the numbers to the D&RG rotaries? I believe the paddle blades on 99200/ OM were more susceptible to damage, but were also easier to fix more quickly.
(Jeff, PBL imported a fine brass model of OY recently in Sn3. Someone else imported OM prior to that. In On3 there were the Durango Press kits, which I think was also duplicated in HOn3. You large scale guys, well, just wait a while and someone will probably help you out).
(Tim, while investment in an OM kit on the resale market might afford you a running start, I am apt to say you will send more to the scrap box than you will use. The blade housing and the blade seem to be most remarked as the hard parts of the build, and the blade would be an excellent project for 3d printing. Not that I am volunteering--I continue to struggle with an O version of the Leadville Standpipe and the S windows for the Leadville Depot).
