This is the information I have found from the ABCC Broadhead Master List and "Broadheads 1871 - 1971".
H.C. Stockfleth from Chatham, NJ filed for a patent for the Nybre on January 4, 1954 and was manufactured by Hilbre Archery in 1954. He also patented the Hilbre broadhead.
The Nybre was a molded nylon head with internal spiral threads so they could be screwed on to a standard 5 degree taper shaft, eliminating the need for gluing to shaft.
Interesting package and information. You can even find Bear Razorheads with another companies packaging.
The patent was granted on December 17, 1957. Not a real rare head but interesting and kind of neat to have them in the Colt packaging. Made by H.C. Stockfleth who also patented the Hillbre head.
