1928 Mercedes S / 630 K owner’s manual supplement.
This is the 680 supplement to the 630 manual in an extremely rare version done for the English market. It’s entitled “Instruction Book for the Mercedes Benz Compressor Model Type S” and numbered ‘6207E 728.’. Though not very thick at 8 pages, this does have the wiring diagram on a separate sheet (6507 b. E.828.) as well a fold-out chassis drawing. This maintenance manual includes very brief operating instructions. The diagram indicates “electrical instruction for the Model K, S, and SS.” This may be the general instruction manual in English for the entire series, which basically had the same chassis with moderately modified engines.
It is in excellent original condition.
