Exhaust pipe routing on a box saloon

[Bob Culver]

My father bought our RP in 1940, and before the mid 50s had replaced the rear exhaust with one fabricated from copper pipe.  Although a plumber he was very skilled in mechanical work and  fastidious and would have copied the original. The pipe is alongside the tank, with the top of the pipe just slightly higher then the bottom of he tank. He was not so exacting about the silencer internal construction so with the copper pipe had excellent note.
