Model 1858 canteens were reinforced by stamping with concentric rings. Collectors refer to these as "bull's-eye" canteens to differentiate them from the smooth sided canteens they replaced.

This one is a solid, Union bull's eye canteen with all three strap brackets, spout, stopper and original chain intact. There are a couple of minor surface dings -- just enough to let you know it was there, and enough surface rust to give it character and evidence of some re-soldering at the bottom. There are no identifying manufacturer's marks. A solid, representative specimen
