Gainesville Bear Grizzly Age?

[Wudstix]

I have a two tone Brown and Green (belly side) Bow has been refinished I believe, serial number is partly gone.  Can still kinda see r08032.  Was wondering if there were any Bear collectors out there who may have info on year this bow was made.  Have it narrowed to 1978, or 1981-1984.  Limb color is dark grey, not quite black.  It has a stabilizer bushing on front.

You can see where the plastic coin broke off, or was removed and the aftermarket bushings for quiver or sight.  Doubt I'll get much closer to a year made, but who knows.

I'm hearing there is not much to differentiate between the years of Gainesville Grizzlies.

Don't know if this may peek someone's memory, but it appears to have grey glass on the back and  black glass on the belly.
