That's a stiff one! Also, difficult to identify. Looks like someone pulled the button off and replaced it with a quiver insert. If it has a Grayling decal then it is late 1977. With Gainesville, it is 1978 to 1984. Random dark limb glass for 78 and green limb glass is 79 - 80. Black glass is 81 - 84. None of those years are FF suitable. Sorry, but I can't be any more helpful than that.
