My late husband and I collected Western Memorabilia. In going through our collections, I have come across a canteen that I have figured out was either used in the Civil War or Spanish American War. It was written upon by its owner at the time. I have tried many, many searches and can't find the person. What is on the canteen is

"H.W. Bigelow

Co. L. 4th

Tenn."

If anyone has any ideas or information regarding this item, I would certainly appreciate hearing from you.

Thank you.
