Chuck, Considering you said your truck is a 1955 1st series and the original pic you posted above showed a “white” existing paint, I think you would be correct in using the Bombay White.
Only thing that would change that IMHO would be if your truck is going to wear “Pure White” paint.
Just my $.02 worth.
PS - The guard you have may actually be a 1954 unit which being “gray” like it is currently would be correctly finished for a 1954 truck. The design of guard for both years is the same. Paint it to match whichever works for you. 😉
