Replica Railbus Revisited

Last year, we showed you some pictures of a replica railbus that was under construction in Grafton, Ill. in this blog post: Replica Railbus.

In less than a year they have completed putting it all together and painting it up quite nicely.  Given what they had to work with, this turned out better (and sooner) than I expected.

I couldn't help but notice, because this is a replica of a one-of-a-kind item that's still preserved, that it has a different paint scheme than the actual railbus currently does at MOT, which appears to be correct for end of service.  Does anybody know what the paint scheme history of the 206 might be?
