When connected to a CO line, it dials out and rings just fine. Click for details. Interesting nickeled hanger for handset. Marked OKI on dial plate , fingerwheel, case and handset.
Case has an applied metal diamond-shaped logo, with blue enamel background.
Model FA-43, Fanon Elec. Ind, Inc., Newark, New Jersey, Made in Japan. This model is made of brass, probably for shipboard use. It apparently originally had a magneto with the crank coming through the front panel, but was modernized with a pushbutton. The handset has a receiver element for each ear and a transmitter that admits background noise on both sides of the element to help cancel it out.
