During my recent Ebay hunting, I found four original Civil War company forms that belonged to a soldier from the 64th New York. Surprisingly, I won all four for the minimum bid. All of them were way cheaper than similar items elsewhere on Ebay. Keeping to our philosophy for providing the fruits of our research for free, you'll find the .pdf files below. All of them are actual size, though make sure to check your printer settings. All the forms should be printed double sided. The forms are all folded like pamphlets. You'll see in the photo how they should fold. I hope these are useful to your impression. For those of you who are curious, without putting a micrometer to the paper itself, the paper is heavier than newsprint but lighter than standard copy paper.
I'd recommend to check back here in our Research Library, since I have a strong feeling this might be a new collecting hobby of mine.
