OK, but this is certainly not well known and I just found one reference to the name.
The Swiss Packard importer Werner Risch apparently labelled his Packards as "Swiss Packard".
I have honestly never seen a photo, and I have looked at thousands over the years, or a reference in several Packard history books I have or have seen that describe a Packard bodied in Switzerland as a "Swiss Packard" but I guess that is the way it was.
