Here is one of my favorite styles. I may not have all of the U numbers correct, I have not yet revised all of my listings with the new guidebook. Top row, left to right: U-499 O-B on ear, U-499 O-B on ear, U-501 N.N. Butterscotch, U-501 O-B R-E on skirt, teal, U-499 O-B on ear. Bottom row left to right: U-499 N.N. Pitt, U-498 N.N. Pitt, U-499 N.N. not sure of mfg, U-506 Thomas on ear, U-499 O-B on ear . All of the ear marked O-B are embossed markings
