Sigtronics SPA-400 Panel-Mount Intercom
TSO'd four-place panel-mount intercom, made in the USA.

Panel fuel flow gauge for light aircraft instrument panels.
A standard round-dial fuel flow gauge for a light aircraft panel, the kind of instrument that is cheap to replace but awkward to find when one sticks or reads low. Supplied as a used instrument. Confirm the dial range, case size and system voltage against your existing installation before ordering.
