From the photo, "Swede" appears to be an officer or NCO with a sword and belt. The TSSD "Swede" is the # 1 man on the gun with a rammer. TSSD also gives us the #3 man at the trail handspike, who also "thumbed" the vent, and the # 5 man that carries the cartridge from the limber chest. Those wounded could be the #2 man that places the charge in the muzzle, and the #4 man with the primer lanyard. I used the CS officer for that function.
Back to "Big Swede," the photo at least shows that there were big guys in CW armies, like the TSSD figure. Funny that I saw the photo as I was working on these figures.
Someone suggested converting this figure holding a Reb under each arm. How about a two Mexicans or two Souix braves?
