LEEA,
Thanks for all the detail. Sadly my Goose (596) was repainted in the early 1990's so I can't offer any insights on original paint details. As I'm sure you are aware, the uneven fenders are actually considered correct on a Goose. Some guys think it's caused by mirrors being attached there at some point in time. However I believe the real cause was part of the original construction of the cars. The example you posted is the worst I have come across so far.
Thanks
-Ryan
