During what years were the Herstal marked HP's produced? What was their significance if any? I recently purchased a '67 produced HP, and trying to learn all I can about them. (Nobody seemed interested in commenting this on the HP forum)

Hello. I'm sorry, but I do not know the answer. I'll bet that if you go back over to fnhipower.com and email "Hunter," the guy who started that site, he can give you the information you want.

Best.
