Hello all!

I previously had my first season part of the 10th Illinois Volunteer Infantry and it was a blast! Thankfully many people in the reenacting world are good people and those in my company let me borrow stuff. I am looking at purchasing some new equipment and have some questions. They are listed below:

What is the difference between Shell and Sack jackets?

What is the difference between the Russet belt and the black belt?

What is muslin lining?

and... what are some basic needs vs. wants to have. This will be my 2nd year out with the company/battalion and want to have the right stuff. I will also be attending Gettysburg so I want to be prepared.
