Adrian, looks like you sure are enjoying the spoils of the hunt. A few still shots of the finds would help to ID them. The large washer with the small hole is a fender washer. They were used to attach fenders to cars like the "T". If that is the same location as the last , you were right the Cimarron cutoff of the Santa Fe trail comes down fromColorado near the Kansas border and goes to NM. I have read many stories of raids on wagon trains going down that trail, but most were in NM. I think the last 100 miles of that trail going into Santa Fe got hit the worst. Frank
