Guys, thank you for the info and pictures on historical sights for a smoothbore. I appreciate it much more than the comments that tang sights have been around since the time of crossbows, so somebody might have put one on his fowler.
I am particularly interested in the mid-18th century, say 1750-1770, in northwestern NJ. My family roots in the Hunterdon/Warren county area of NJ date back to about 1750-1760.
I'm well aware that TVM's fowler is not necessarily PC/HC for that time/place. However, it is at least a fair representation of an early American fowler. Eventually I would like to have a gun built that is more HC/PC for the time and place that interest me, but at this point in my life it just is not an option. However, that doesn't mean I should just slap on whatever sight might have been used by somebody, somewhere, on a fowling piece from any time in history.
While I know that rear sights were not uncommon on fowlers, I would prefer to not have one. My shooting style is better suited to using a front sight only. I have been shooting shotguns for at least 30 years, but my experience with rifles and rear sights is rather limited. To be honest, I have never fired a CF rifle. I struggle with rifle-type sights as my shooting style is more instinctive, point and shoot. The problem I find myself faced with is that NJ’s law may require me to use a rear sight if I want to hunt with a single projectile. I am trying to decide if I should have a rear sight on the gun (a question that only I can answer) and if so, what type of sight would be most appropriate.
