    Both the P35 nd P40 had ribbed manifolds. The in late 1928 or 29 they came up with the accessory muffler for the P35 and P40 which was the "box" shapped part riveted to the round tube. This was also the mounting point for the accessory underwater exhaust.

    The P30 has smooth manifolds and I know with certainty that they are one year only parts.

    Hope that helps
