Welcome to the Imperial Club, Manfred. A prewar Imperial is a welcome addition. My 70 Years of Chrysler book shows the CH series five passenger sedan as costing $1,945 and production of 1,002. A shop manual & parts book are very helpful in a restoration. The only Literature Dealer which comes to mind is Walter Miller. Other members may offer suggestions. I ordered the correct fabric, (Seats, headliner & carpet) from LeBaron who advertize in Hemmings. Pictures, before, during and after restoration are recommended if you don't have a better memory than I do. :) Congratulations on your "new" Imperial.
