My goodness...I do love looking at old heavy bows, however, looking at them is all I could do these days.
I've had a few over 60# and think I only had one (Kodiak Hunter) that was 75#. I have sent them all down the road, but do like seeing posts about them.
Most bows being built, sold, traded today are in the 45-50# class, so I expect Bear built bows in the early days that reflected the same.
