That one is transcribed "as is" from the original notation in the Buckley 1860
This one is how I fingered and played it
I don't know if there is other tab for this out there....but here is one now
LOL, I got halfway thru tabbing this out back when we were playing at Antietam in the barn. After watching Greg Adams play it, I gave up. More complicated than I wanted to deal with...I enjoy the simpler stuff too much.
Your tab looks excellent, of course. Well done!
