The Cravotta Brothers of E. McKeesport, Pennsylvania sold a pretty good middle-of-the-road line (Black Hawk) of bows, quivers, and other archery items in the 50's, 60's, and even into the 70's. I've heard that one common flaw to watch out for is the lifting of the fiberglass, but I've never experienced that personally. Otherwise, they shoot pretty good and used prices for them are relatively low. In other words, not a bad bow for their prices.
Someone told me these bows were easy to date since over 95% were marked with the month and year of production in the first 3 numbers of the serial. So if your bow's serial # starts with a "763", then it was made in July, 1963.
I'm sure others will chime in with more info as well as help on your Herter bow too.
