We are working on an x-Santa Fe caboose and have located in Osage County, Oklahoma the steel frame of a wood Frisco caboose and a steel Santa Fe caboose. These we caught in a grass fire several years ago and I believe the owner is getting ready to sell. The owner has the numbers but they were not handy when I called him this morning. These are rough but the Santa Fe Barber-Bettendorf caboose trucks might be very valuable to someone, and a wood caboose frame might have interest also as a BIG project. Tom Birkett, Bartlesville, OK
