I think that is a good way of showing the muti-ownered past, a number of C&S cars ended up on the RGS and only a few survived so why not have the opposite side in the later owners lettering? Just like the #74, should be C&S on one side with RGS on the other(after the C&N-W lettering expires).
I wonder just how many would notice, given the lack of knowledge thesedays?
