This is a (standard) Eight convertible sedan photographed at the PAC national in Ashville, NC some 20 years ago. Owner was Bob Woolfit of Virginia. Adjacent is what appears to be a 1934 Super Eight convertible victoria by Dietrich.
The 1941 custom cars included two Darrins (victoria and sport sedan), two Rollsons (all-weather cabriolet and all-weather town car), and 3 LeBarons (touring sedan, touring limousine, and the pictured sport brougham. Of these, 99 were built and about 35 are known to remain. .
Some folks find it interesting that a full, one-off custom would be built on the 160 chassis yet the explanation is quite direct. Formal broughams on short wheelbases were quite in vogue in that era, and as Packard didn't offer a naked chassis to custom coach builders and given that most of the body and interior would be removed and scrapped, why pay for a 180. .
There weren't many one-off customs on the 1934 (standard) Eight chassis and even fewer by European coachbuilders; this is chassis 1101-28 and was photographed at the Centennial in Warren OH in 1999. Originally built for a Ferdinand Thun who immigrated from Germany to Pennsylvania where he made his fortune in textile industry. Bosch headlights and electric wipers of course.
