Keith-
The units came from the factory with only the striping and lettering in paint. Everything else was Stainless Steel. There was some variation in the level of polish but I would just go ahead and paint everything in Alclad Stainless unless you want to research all the photos available and try to develop an area by area diagram of varying Stainless Steel finishes.
The upcoming Kato unit will first be offered in the As-Delivered scheme… Black stripes. The unit at IRM has a replacement pilot (there were three different styles of Pilots on the E5s as delivered) and the IRM version is one style of the replacement regular steel pilots which were painted silver(some had what look like E7 pilots applied which do not follow the contours of the originals).
Check photos for the unit you are doing….you may want to match the “phase” of the unit as well… the Valerio shell, being based on the LifeLike E6, is closest to a Phase II (the Kato will be a PhaseI which is like an E3 with the parallel to the rails roof radiators vs. the perpendicular style of the E6).
