Regarding Bob R he said that he happened on a former employee who was charged with burning records but that seemed like alot of work. Bob said he gave him $40 and comenced hauling paper out to Alamosa Doctor Chione had a "paper" removal authorization letter from the receiver and he also removed paper. Plus there were individuals who removed bits here and there. This all happened after the CSHS had been given first crack at whatever records they wanted.
I have never asked about Durango trainsheets surviving but I will. I'd be surprised if none exist - other areas do.
