Vintage NOS Seth Thomas Brass Marine Barometer Helmsman Never Installed USA Made. We bought this barometer and the matching Clock (See other listing). From a Marine Hardware Store that was closing. They both sat on the shelf for years, and are in nearly un-used condition. They have never been installed. It’s hard to find anything made in the US anymore. They are both very high quality. The Barometer measures 8 1/2 inches from the top to bottom. And it’s 3 inches thick.
