Hi All, I want to build the F-117 Stealth and a few other aircraft models by GPM, but I have no knowledge of the notations GPM uses on its models. For example, a "W" inside a white area seems to mean you cut out the white area. Is this correct? An "L" and a "P" in a part's designation seems to mean that it is a left or a right part. Is this correct? Please explain all of the notations, symbols and conventions you have encountered on GPM models. Please! Regards, Bill M.
