Jim - Nice insert card. The Razorhead Patent number on the card indicates it was made after the patent number was granted on April 8, 1958.
Prior to the patent, the cards read "U. S. Patent Applied For"...
Also note the difference in the Bear Logos...
The original production inserts had a hole in the front and were not blued. This photograph does not depict the bright, shinny, non blued surfaces very well. The insert tool had a flat non-blued surface. Just pointing out more items for us crazy collectors to look for in our never ending searches for different Bear Archery Products.
