He continued primarily a professional welterweight boxing career until around 1940, when he served as a Marine in World War II, before returning to start a dry cleaning business in his home of Fall River, Massachusetts.

[3] Bor won his first professional bout with a second-round knockout of Al Hope on October 5, 1932, at the Casino in his home of Fall River, Massachusetts.

[2] In a disappointing turn that ended Bor's long early career winning streak, he lost to the somewhat heavier, more experienced, and likely more talented Babe Marino on October 21, 1936, in a widely anticipated eight round main event at the Auditorium in Oakland.

Due to the bout's potential importance and Bor's successful record, he was trained by two well known former contenders, Jimmy Duffy and ex-light heavy champ Tommy Loughran.

Early in the bout, Bor suffered a bad cut over his left eye, which grew worse until the referee stopped the fighting 1:05 into the ninth round.

After the war, he returned to Massachusetts, where he first worked as a foreman at the Eastern Sportswear Manufacturing Company and then opened the Olympic Dry Cleaners in 1948 in his hometown of New Bedford.
