Morse-Beauregard is a historic brand of motorcycles.
The company name was: Morse-Beauregard Mfg. Co., Detroit.
This was an American company that built interesting 492cc-tandem twins since 1912. The drive could be done to the customer with a cardan (homokinetic coupling) or chain. Probably the company moved to Buffalo in 1916 or 1917, where production under the name "MB" was continued. There, 746cc two-stroke parallel gains were built until production ceased in 1920.
