This is a single used headlight lens with stainless ring and spring toggle.   The 9" diameter lens has FORD logo at bottom and the words "Twolite Headlamp" below that.  There are at least three dents in the stainless steel ring.   It appears to match the 1932 headlamp lens, Ford part number B-13060, as illustrated on top of page 528 in Ford Chassis Parts & Accessories Catalogue dated November 1950 - the "green bible".
