Another thing to consider is that brake parts from Weinmann, Phillips, and Schwinn were all available at the same time for a period in the mid 1950s. Apparently there was at least some overlap in the brake equipment being used for a time. Perhaps the transition from Schwinn to Phillips to Weinmann was not entirely clean, with bikes of the same year sometimes showing up with different brakes. Of the three brake types, the Schwinn Built are the most collectible, though the Weinmann 810s probably functioned the best of the group.
