I received a reply from the seller that said the data plate had 5479-1. The PAC roster keeper for theses cars has a paint code of "S". Not a 54th series code, but a 26th series.
I do not know the straight eights, but was told long ago that the convertible shown in the sales brochure, with the blue interior was not offerd to the public.
A leftover 26th body used for 54th publicity?
