Back in the '50's there were no Tamerlanes or any of the other tournament or target bows that Besr was known for. The Kodik Special was probably the top of the line Bear target bow at that time. You see many of them in target weights, more so than Kodiaks.
With this in mind I am certain that the bow pictured is a '59 or '60 Kodiak Special that someone modified to add mass and stability. As a testiment to that forward thinking person, look at what Bear did in '63 with the Tamerlane. They made it longer with a more massive riser. It developed into one of the most popular tournament bows ever. If the guys dad did it, he was way ahead of his time.
On the other hand, Bear did put out a few prototyps as experamental bows that never really went into production.
