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.
