I grew up about 30 miles west of Herter's, which was in Waseca, Mn. Consequently, much of my early hunting gear was Herter's stuff. Went there often, the place was a kind of combination sporting goods store and museum where all the neat artifacts & trophies the Herter's had collected was displayed. Heady stuff for a kid in the 60's. I still have & use Herter's decoys I bought as seconds from their closeout quonset on the back lot.
Used to shoot both Herter's & Bear fiberglass arrows back in the late 60's/early 70's. If I recall, they were outlandishly heavy for the 45/50 pound bows most of my crowd shot back then, on the order of 900 grains for a finished 30"-31" arrow with a 145 grain Razorhead!
They were tough but when they broke it was nasty, with that linear fiberglass construction...
