The year 1931 was the last year for the Stutz M series, now called the MB. This example has elaborate coachwork by LeBaron on the long 145 inch wheelbase. It was powered by the 322 cubic-inch Stutz overhead valve straight eight, now rated at 113 horsepower. LeBaron was purchased by Briggs Manufacturing Company in 1927 but continued to supply high quality coachwork.
