Reskin for the M53/55, based on the restored M53 on display at the American Military Museum in southern California (a.k.a. "Tankland").
Additional background: A number of years ago, I had the pleasure of visiting the American Military Museum. The museum itself has no shortage of interesting vehicles (and not just tanks), but one in particular caught my attention -- a dark greenish-grey M53 towards the center of the museum grounds, with the words "Bringin' the Rain" painted in the side. While the art may not have actually been present on the original vehicle (this appears to be an addition from when the vehicle underwent restoration), this added a very special detail -- something which gives it character, while remaining true-to-period. I wanted to replicate this in World of Tanks, and so, here we are!
