Thanks Carl for taking the time to post such good information. It is much appreciated! The rifling on it is slight, and I’ve never really got magnifying glasses and tried to find out. I will do that soon and see if I can determine the number.
The other problem I run into is that The Vicksburg Park does not list a single 3.3” gun serving there. Mine was found on private property and I’m sure the cannon that fired mine eventually retreated into Vicksburg. In the ORs the Confederate Chief of artillery lists that only two 3.3” served there. But we know they were used at Vicksburg. So when I talk about a 3.3”, people often site to me that there is no such listing at Vicksburg, and again question me as to whether I’m sure that’s what I have. It’s kind of frustrating.
Anyway, thanks again!
