AD original wheel questions.

[ghettoluxury]

I have a '49 GMC and I would like to keep the originality of it, with a little flare. So I have a few questions about the original wheel color options. I have always thought that they were black from the factory. The problem is that I have seen black, tan, white, silver, and even body color. So what is correct?

Looking at old advertisements has been no help either. Both Chevy and GMC ads are all over the place, some have color matched some are not. The few GM file photos I have been able to find had black wheels on the trucks. I also know that the added pinstripe was an option. My truck has an apple green stripe around the belt line, so adding it to the wheels would be ok with me.
