Well I figured instead of a new thread; I'd revisit this one.
At the Jefferson Civil War Symposium in Jefferson, TX last weekend, I got to see this jacket and speak to its owner who've I've seen around and spoke to in the past but was ignorant of this treasure in his possession. He was extremely generous as always, us going over the jacket's history and him showing me it in detail. Later the well-known Fred Adolphus and I got to talking and catching up and the jacket's owner allowed us to pick it up and really study it! When a few strings of the cotton warp fell off he told me I could keep them, and I've never been so excited over tiny pieces of string in my life!
There is a LOT of differences in this jacket from your normal "Columbus Depot" jacket. Its made of cassinette/cassimere or a jean similar to it, some details of the cuffs are different, has an interlining in the front much like a frock coat, two flower citizen non-functional cuff buttons, the blue flannel trim is twilled and put some folks in the mind of Federal trouser materials, and so on. I know the sweat stains in the lining kind of hit home for me, it being sweat for Southern Independence. This jacket may not be a depot jacket, but a tailor-made, or even homemade copy, with several small details making me lean towards possible home-made. I'm not sold on that, but it very well could be.
I'm not sharing all the photos and so forth I took, just a few. Its owner wasn't too against me doing so but I've no intent of abusing it.
I know getting to examine the jacket was an awesome experience, and doing so with one of the top, if not the top, Confederate uniform researchers also made it an enjoyable and very educational experience. I know we were both snapping pictures and pointing out stuff we were noticing much like kids in a candy store. But were very careful with this irreplaceable artifact. And its owner and preserver was beyond gracious letting this happen, him also pointing out numerous details.
I know I plan to make as close a copy for myself as I can with my meager skills just for the heck of it! I ever get to attend a reenactment east of the Mississippi again it could come in handy. I've been blessed enough to see and look over several CW jackets, but this for me was very privileged access!
Also, if anyone out gets to thinking Jenkins wore it home this ragged, I'm just gonna come out and say it, I will bet most of the damage came AFTER the war from moths and so on before it became a historical treasure.
