Answer
Hello Ken and thank you for your inquiry. The only mark that I can find is the Rosebower trade mark of 3 interlocked rings manufacturer M. B. Bryant & Co., Inc. 136 W 52nd Street in New York. They were active in the 1930's. You can see an image at the below webpage. Just copy and paste the url into your browser address field and hit enter:
