Old,
I cannot speak for Greg Davis and I am not. What I am posting is personal knowledge of Walter's manuscript and his final days, the time period 1983 - May 1984. Something you need to understand about Walter Gassler's manuscript. Walter hand wrote the manuscript and gave it to Robert Lee at San Diego, CA. Lee was an author and film producer with his own production company in San Diego and Los Angeles. Walter wanted Lee to rewrite the manuscript into an acceptable Lost Dutchman book or production video. Walter and Robert Lee corresponded back and forth through letters and phone calls and were working on an arrangement when Walter went into the Superstitions in May of 1984 and tragically died.
Lee was left with Walter's manuscript and rewrote parts of it but never finished or finalized the work. With Walter gone the production video was out of the question. There was a final chapter Walter was working on, something he had started back in the mountains and his last trip into the Superstitions would have given the manuscript the ending it needed.
A few years after Walter died, Robert Lee himself died and his son Randy took over his fathers production company. Sometime about 1995 Randy Lee turned over all his father's things including Walters manuscript to Greg Davis at the Superstition Mountain Historical Society with permission to do with it whatever the museum wished. His only stipulation being all his father's material be preserved. Anyone can access the Robert Lee collection at any time, an appointment may be necessary.
Few people have ever read Walter's hand written manuscript. It contains things not included in the typed copy but those things are incidental and no great secrets were withheld. The manuscript has been typed on at least two occasions that I know of.
This is my understanding based on having been with Walter in those last months and knowing what he was trying to accomplish and who he was working with.
