The new Series ''M'' was introduced at the end of 1930. This model was as unique and breathtaking as the Model ''K'' was beautiful. The front fenders flared up a bit and pointed straight forward. The headlamps and grille had a distinguished rectangular shape, high and narrow. The disc wheels were smooth cones. The design remained as a Checker feature for a number of years until after World War II. The seat cushions were filled with down, and when a passenger would leave, the cabbies would reach in and fluff them up with a special little paddle that they carried.
