Vintage Stewart Warner 2 1/8 0-80 psi needle mechanical oil pressure gage 331

  

One excellent used Stewart Warner 2 1/8 inch 0 - 80 psi black face with full white needle mechanical oil pressure gauge. The gauge is in very nice condition with no issues that I can see.

The gauge has been tested and works as it should. It has the socket in the rear case for the back lighting.
