Brian, you have sure come to the right place to learn about your grandfathers items. As mentioned, there is a wealth of knowledge here, and many who really enjoy seeing some of the history of the sport.
PowWow is the main forum here, and the place that the most people will see it. But another excellent forum for things like this is the History/Collecting forum. You will find it listed under the main forum page. There are people that hang out there with a wealth of knowledge about old archery gear.
I'm sorry for the loss of your grandfather, but happy to see you keep his legacy alive. He would be thrilled!!
