Well, I dont know what yr FSM u are referring to that can be washed, but the 61-71 CAN NOT BE! Those yrs they were light weight paper, not even as good as basic 20# copy paper. I bought a 70 FSM NEW from the dealer in 78. It fell apart YRS AGO. I also have acquired a couple others in recent yrs, as well as a 62 FSM. ALL are falling apart, have pages that have yellowed with age, dog eared and torn. I keep them on a shelf in my office, they are not abused. The new reprinted 66 I got 2 yrs ago is 100x the qlty of an original. Bishko sounds familiar, may have been the source. Trey linked me to it at the time.
