Scored on some old Smith Cobra broadheads from the early 50s.  A two blade head that has a somewhat ‘H’ look from head on.  Kind of an SR71 Blackbird vibe to them. I tried the American Broadhead Collectors Club but their Facebook page is locked for members only.  Google only gives up a recent mechanical contraption.   Anybody know anything about these heads or maybe used them ???  They look really cool !!!  I wouldn’t mind actually using them if there aren’t negatives attached to them.
