i have the title for my 52 and the serial number reads 14 2KRL4 356 which reads 14 - Baltimore, K - 1952, R - 3600 (3/4 ton), L - December, and then the last numbers are the production #s. What i am unsure of is what the 2 before the K means and possibly the 4 after the L if 356 was the production #. I entered the # in the vin buster http://www.stovebolt.com/techtips/vin/vinbuster.html but would get the wrong info unless I took out the 2. I have to get a plate for the door post soon and imagine I would just stamp in exactly what the title says. Im just making sure everything goes smoothly. Thanks!
