Jacob Bromwell's company has been making these tin cups since the 1800s (as well as other cooking/camping supplies). Handcrafted in small batches using the original equipment since 1819, without welding or soldering.
The merchants of "mostly made-in-the-USA gear, gifts, and goods for men" Owen & Fred are offering to send you one of these neat tin cups ...
The Owen & Fred site has a few known faces (Topo, Ursa Major ftw) and generally lots of rugged bar/kitchen/office accessories. Nae bad.
