There were a few employees working on bows during the Transition Period. At the point when Grumley left, Meaker took over Grumley's position as the head bowyer at Bear Archery.
As you can see from the photograph of the 14 bows, the term Transition Bow is a very broad term used to describe a variety of differently constructed bows as the evolution to the Grizzly progressed.
As luck (or the Bow Gods) might have it, I was truly more than fortunate to acquire most of Meaker's personal bows. His bows filled in many gaps in what is perhaps the most confusing puzzle and least known era of Bear Bows, the period from Grumley to Meaker to the Grizzly. After studying many of these bows over the past few decades, it is pretty easy to see the differences in Grumley's work vs Meaker's work, that is when I have the bow in my hands, but not always so easy to pick up nor illustrate those differences in photographs.
It seems that people need to label things so for the sake of simplicity in explaining the collection to the general public at a show, I usually don't get into the detail of the Transition bows as most people quickly get that blank stare on their faces as they reach that point of information overload. At that point, you know they are lost.
