Okay, at first I agreed that digging a hole might be a good idea. But your persistence has made me get up and do some research. The serial number you posted can not be correct. The prefix 37 indicates that this is a model 137, or the long-wheelbase Series 13 from 1929. Franklin always used suffixes to indicate body style. The number 3719727FL2 is not a Franklin car number as it is. Most likely you missed the last digit, and the third from last should not be a letter. All of Franklin's suffixes end "L**" with the last one or two numeric digits indicating body style. (In case you're wondering the L stands for left-hand drive. Overseas you might find a suffix beginning with R.) For a model 137, the choices were: L23-Sedan; L24-Oxford Sedan; L27-Dietrich Speedster; L5-Limousine; L28-Sedan Limousine; L29-Town Car; L22-Touring; L1-Sport Touring; L2-Sport Runabout. So if it does indeed end in L2, you have a roadster, it's unlikely though. It's also interesting that you have one of the latest Series 13 known, with the end of the run being car# 197288. Considering the condition of the remains, parting out is the best route to take. 1929 was Franklin's best selling year, so parts are always in demand. To restore this thing would cost many times what the car could ever be worth. Franklins generally do not bring the high prices that other classics do. I dragged home a 1923 Series 10 sedan last year that is better than what you have. I sold alot of it, but alot of it went to the scrap yard. Yes a series 10 is much less desireable than a 13, but ratty sedans are still ratty sedans.
