As mentioned by other members, I may be of some help. By the Serial number we'll be able to give you the year. 1911's S/N's ran from 300 to 588, 1912's S/N's were 589 to 920 or so, 1913 S/N's were 991 thru 1590 and 1914 S/N's are 1591 thru 2098. The engine number would be nice to know as well, but there's always the chance it had been replaced thus we don't use that for year identity. Mercer Associates, for which I keep the Roster of all existing Mercers will be glad to help you with any questions on your car. STAN
