1936 Rolls-Royce 25/30 Sedanca Coupé by J. Gurney Nutting

GRM 7roadUnited Kingdom
Engine
4.3L inline-six, F-head, single downdraft carburetor, ~90 bhp

Chassis GRM 7 is a 1936 Rolls-Royce 25/30 carrying a Sedanca Coupé body by J. Gurney Nutting, designed by John Blatchley and identified as their design study number 266. Originally delivered through H.R. Owen to a Buckinghamshire buyer, the car subsequently emigrated to the United States in the early 1950s and entered the ownership of Nelson Rockefeller. Later owners in Arizona and Ohio cared for the car, which underwent a restoration that earned concours recognition. The Sedanca panel has been sealed in the closed position and the older refurbishment now shows age.

Maintenance & restoration

  1. Restoration

    A comprehensive refurbishment was carried out at an undetermined date, resulting in a finish that earned concours-level awards. During this work or around the same time, the Sedanca roof panel was permanently sealed in the closed position.

    The restoration has since aged; the paintwork, likely a lacquer finish, has begun to craze in areas of heavy use and near ground-level openings.

  2. Modification

    The Sedanca sliding roof panel was fixed permanently in the closed position, possibly during the refurbishment period or independently prior to it.

    The prose suggests this may have been done for practical reasons during leaner economic times; the car remains in this configuration.
