Anitque Train Orders

I found a batch of train orders dated from 1907 stuck behind the retainer of D&RGW caboose 400 at the Colorado Railroad Museum Sunday. This was after the public runs and we were pulling the caboose off the Table Mountain Spur so we could put the Union Tank Car line car in the spur. Since the caboose was off by itself it was only by chance that I found them.
I don't know of packs of these orders were left at other places at the museum before, however, several packs were left one cars at the Pueblo Railway Museum in the past. The orders appear to be authentic. Outside researchers have matched these orders against train sheets that were in collections.
I checked withg Ron Roach at the PRM and no orders have been left there in more than a year.
