I'm building my first gun (a fowler). I was fortunate to be able to go to the CLA Show in Lexington last summer, and took lots of photos of fowlers, which has been very helpful to refer to during my build.
Pretty much all I have left to do is solder on the front sight. Like any modern gun enthusiast, I just automatically assumed that I would locate the front sight near the very end of the barrel to maximize my sight radius. However, when I look at all the front sights of the original fowlers I photographed, I notice that while some put the sight up close to the end of the barrel, most locate the front sight several inches back. Why would they do this? At first I thought it was to make room for a bayonet - which is clearly the case on a couple of them - but most are clearly not made to fit a bayonet. Is it to make it more comfortable to hold when ramming a ball in? Does it give you a secondary elevation mark for long shots?
Here's some photos of the fowlers I'm talking about below:
