Hello. I was wondering if anyone could identify what year and model of automobile this headlamp is for (if any). From what I gather, Corcoran began producing automobile headlamps in 1905. This is similar to one that I've seen identified for Buicks, but this one is longer. I don't believe the Ford Model T used Corcoran lamps until 1914, at which time they were steel with brass trim. Overall length is 8 1/4 inches, outside diameter of the door is 7 1/2 inches, and fork width center to center is approximately 7 1/8 inches. Thank you!
