Bill, I have one in pristine condition, although I probably know less about it than you do.
One thing I love about mine is that has about the most irredescent piece of Bubinga I have ever seen. I have an Ultra Mint Bear Kodiak Dogleg with the same irredescent wood. When you take them out into the sunlight, they look like they have veins of gold running through them. Of all of my other Bubinga bows, these are the only ones with the irredescent quality, so I assume that it is just a freak chance on these two particular bows.
However, maybe Harold Groves made a point of using irredescent Bubinga on that particular model, thus the name "FLAME HUNTER". What about yours? Does it have that irredescenst look to it.
Possibly mine only still have it because they are in such pristine condition. I wish all of my bows were in that great a shape.
Most Groves bow will really "rocket" and arrow. This is probably due to the "dyno-stressed" construction.
Groves bows were glued up in two stages. First one set of laminations (glass and inner core wood) were glued to the riser at a certain angle in a bow pressed. Once this stage was compleated, the other piece of glass and inner cre wood was added in a differend bow press with a different angle. In other words the back laminations and the belly laminations were glued in under differet pressers or "stress". thus the term "dyno-stressed". To the best of my knowledge, Groves was the only bowyer that did this.
I am sure that someone out ther can give a better explanation of how dyno-stressed bows are constructed and what difference it makes, but with my limited explanatory skills and knowledge, that's the best I can do.
