Was working on this video of the 60's material and noticed that 476 seemed to have a stack extension(spark arrestor), in 1965. In addition there is a small tube or pipe running behind the stack. Anyone know when this started. Seemed like 1965 from my films, or the year is wrong!
Also the piping seemed to be gone in 1968.
Also, was there a special bracket on the side of the cabs to hang waterbags. Waterbags were cool, but they kinda made it hard to tell what number the engine was from the side, especially when it was either 493 or 498!
