1929 Duesenberg Model J - Page 4

1929 DuesenbergDuring the restoration, every critical part was magnafluxed and checked for cracks. Exhaustive research and access to engineering drawings ensured that every component, no matter how minor, was returned to factory tolerances or better. An intensive program of research was undertaken to ensure that each detail was faithful to the original materials and finish.

The balance of the drivetrain was complete, but every component required both mechanical rebuilding and cosmetic refurbishing. The entire system, engine, gearbox and rear end were completely disassembled and every bearing surface, gear set and actuating mechanism rebuilt or replaced.

It was discovered in conversations with the historians within the ACD Club that the crank-up second windshield, although not originally fitted to J116, was installed shortly thereafter by Derham. As originally constructed, J116 was fitted with a conventional folding tonneau cover and windshield. It is interesting to note that the crank-up window fitted later by Derham would prove similar to that used on the firm’s Tourister design, making J116 in some respects the missing link between the two styles.

While most examples featuring the external pipes also had the shuttered radiator grille (and its longer hood), J116 retains its original honeycomb radiator.

The interior trim and upholstery is identical in form and pattern to the originals, as is the top and its liner, which were painstakingly cut and fitted to match the original patterns. Each instrument was restored, and a new wiring harness fabricated for the complete car. Each light, bezel and lens was carefully rebuilt and reinstalled.

The woodwork was carefully re-veneered and properly refinished. Hundreds of hours were dedicated to careful blocksanding and preparation for painting. The finish, a very elegant combination of greys, was color-sanded and buffed to provide a superior shine and finish quality.

The restoration was completed in early 2007. At this point, the car was invited to participate in the 2007 Pebble Beach Concours d’Elegance special display honoring the “Year of the Duesenberg.” The same year, the car completed the Pebble Beach Tour d’Elegance, successfully and without issue.
