That bow...and most of them for that matter, because I love the length, weight, etc....plus I don't always need to find new arrows...is 64 inches, NTN, and about 65 or 70lbs at around 28inches (my draw). In those days, there were not many folks making "wood bows" anywhere, let alone in MT, and access to good wood (osage, or yew, or other) was very limited. So I picked through whatever hardwood supplies stocks I could find, and really, I cut my teeth learning how to tiller and design bows out of boards. Now that I have access to good wood, I prefer staves, but those early board bows performed every bit as good and many of my best selfbows do now...and there is no better way to learn the craft without breaking the bank, than to learn on board bows.
BTW, that cow was killed in late January, sub-zero cold. I worried that the bow would blow apart when I came to full-draw! Of course it didn't....
That used to be a great late-hunt for archery-only here in SW MT, but wolves have put an end to that....another story altogether.
