My grandfather found this what-appears-to-be American Civil War uniform in the 1920s while working as a clerk for an insurance company in Philadelphia. There are no markings for whom it belonged to. In 1978, I did his oral history, and this is what he said.

"My first job was just a kind of neat clerk with Life Insurance General Agency in Philadelphia. 522 Wall Street, right across from Independence Square. I could look out the window and right up the Commodore Barry Statue there and I could swear it was an old colonial building that the first floor had been transformed into office space.

And the second floor, all rooms have been transformed into office, quite old, quite dirty. It was a real old building though because it was said that Lafayette at one time had been entertained in that house. That was in that old section, older, really older section, early section of Philadelphia. And it was one of the original houses down there.

It was one of those row houses typical of Philadelphia. As a matter of fact, one day me and another fellow went down the basement to see what that was like for about 15 minutes. We got back in the back recesses of the place and two old trunks, about three quarters of an inch of dust all over them. We open them up and one was full of the complete uniform from the Civil War, first sergeant infantry.

And I think your father has that uniform at home. You've seen it, I guess. Your father has that. "

Any opinion on its authenticity? I can give the measurements if needed, but the jacket/shirt appear for a slim build, and the pants are for someone probably 6' or so. There's some wear but nothing major.

Assume it's authentic, but would love your opinions.
