This is a cool and hard to find desk clock from Richfield Oil Co. It is aviation related in an airplane engine shape with a propeller on the base. This clock, designed by Curtiss retains much of the original green paint and some of the felt on the bottom. Measures approx 6.5" tall x 5.5" x 2.25"

Very good condition for age.  As shown in photos, wear to the green paint, crystal over the clock face is cloudy, but should be able to take it somewhat apart to clean.  It has been tested and in working condition. Not tested for accuracy
