Some of the most unique issue sack coats from the Civil War came out of the small Steubanville Depot in Steubanville, Ohio. Believed to have been set-up to help make garments for the large Cincinnati Depot, these coats really are quite unique.
The Steubanville blouses are unlined in the body, but have muslin sleeve linings. The coats have a 4-piece body, and all seams were felled by hand. Most unique of all, these coats featured an external patch pocket with a curved top rather than the internal kidney-shaped pocket seen on most contractor-made blouses. 
To ensure a proper fit, please make sure to get accurate measurements.
