I would assume for safety.......keep that mirror as close to line of sight as possible.Also the reason the turn signal lever is on the right side.......so the same hand is off the wheel as when shifting.
I think you may find that when the 4104 was first built, turn signals were a very new device and were actually an option, even in automobiles, up to the early 50's. I really do not think a standard had been established for the placement, either on the right or left side, at that time. I do not recall them being standard in trucks till several years later. I do not know if the earlier busses had the built in turn signal switches or not. I know I installed external turn signals on a lot of cars during that period of time.

Actually, the 4104 turn signal lever was on the right side. It was easilly rotated to be on the left.Len
