New 5000 psi stainless pressure gauge navy buweps -4 an
This item was acquired at a military surplus sale a couple of years ago. They are brand new in the original factory boxes and heat sealed plastic bags. They were made by QED Inc, which specializes in miniature gauges and other precision instrumentation for the US military and aircraft manufacturers like Boeing. Best I can determine, these gauges were originally made for the MX missile, which was to be the cornerstone of the US nuclear arsenal until arms treaties limited its deployment. Considering their intended use, the quality should be sufficient for anything you plan to fix in the back yard.
With a only a 3/4" lens, you won't be able to see them from across the building, but the dial and needle contrast very well, and they are easily readable from 3 - 5 feet. For an aircraft cockpit or a dense instrument panel, they would fit nicely into the confined space without crowding everything else. They are drilled for safety wire on opposing corners of the hex wrench surface, so they won't loosen and fall into something expensive.
QED still makes the Model 0750, and a datasheet is available (small PDF file):
