LW37 is the only factory built Silver Ghost service vehicle Rolls-Royce produced. It was built to provide service personnel with a dignified method of visiting the Silver Ghost owner's estate and if necessary, removing their car to the factory service facility. Prior methods included utilizing Ford TT trucks with wrecker derrick - not at all fitting for the transportation of a Silver Ghost. It is specially equipped with four-wheel brakes and a special tow bar that connects to the rear fitting and has a casting that fits a Silver Ghost front axle on the other. With this arrangement, one would have to look carefully to see the car being towed is not actually moving under its own power. It also has tool boxes built into the rear bed area to be utilized by service personnel when visiting a customer's premises. It is interesting that the front portion of the cabin is exactly like that of current production Brewster limousines of the period, except it is lower and sleeker. The 'fit and finish' are the same as the coach built cars, including the special rear body.
