Renaissance Man - As Glenn St. Charles always says, "I will give you five bucks for it".
Seriously, the value would greatly depend on how well the arrow could be authenticated, e.g., photographs of Fred with arrow or if the arrow's crest appears in a Bear Catalog, etc... You will first have to establish with documentation of the era that it is an arrow produced by Bear to really have some value.
I've exchanged items with Deano many years ago and know him to be an honest and fair person. I would not doubt anything that he would say. If Deano has any photographs of the hunt, they may be able to authenticate the arrow as being one of Fred's.
The Razorhead is a 1964 model which was made until 1978, which gives you a starting point to search for the arrow in a Bear Catalog or photograph.
I collect old wooden Bear Arrows from the 1930s to 1960 and have many arrows signed by Fred as well as several of Fred's personal wooden arrows including his oldest known Big Game Hunting Arrow, his 1945 Moose Arrow, and the actual Arrow he used to kill his Fallow Deer.
My expertise in this field ends in the early 1960s, so I can not be of much help in dating your arrow.
Fred's wooden pre-1960 personal arrows that can be authenticated in photographs or films start at the bottom of 4-figures.
I would seriously doubt that one of Fred's 1964-1978 arrows that was not used for a kill arrow, could come close to 4-figures. But you never know what the final sale price will be for items that are put up for auction...
