I won this Door Prize back in 1975 at the YPCIC show. What a suprise when they called my number. It was the first insulator show that my father and I attended. Great show and very friendly people. That was the begining for us in the hobby. The insulator is what I believe to be a U-282B in Cobalt Blue but I don't see that listed in "Jack Todd's" book. I would like to know the correct U #, so a little help would be appreciated. 3 1/4 W X 4" H

Thanks for looking.
