From my Brooklin Collectors Guide (pic).
The 1998 W.M.T.C. is a very special model because it comes with an open hood and engine detail. Engine option is the big straight 6 as detailed in the 1952 catalogue and the model is supplied with a separate hood which fits the model in the open position. Color is French grey with a pale blue grey interior, pale blue steering wheel and dark blue tonneau. Furthermore, this special casting is unique to this model run and does not appear later as a standard. This model was limited to just 250 pieces and presented in a special box.
