Unknown Garden Tractor

I need help in trying to identify this old garden tractor. It has a Ford car 3 speed transmission (about 1939) with a Ford car 9' clutch and a Ford car rear end (3.78 to 1 ratio) with large drop boxes and 4' band brakes. It has an inclosed drive shaft from transmission to rear end. Has Ross steering box. Frame is made out of 3' channel an is 14' wide and 67' long and has the numbers 1-17 stamped in it twice. It has a 60' wheel base. It has 16' rear wheels with 8-16 bar tires, and cast iron split front wheels with 4.80-8 tires. The original color was red/orange. Do not know what the original engine was. There are 12 part numbers cast into different parts through out the tractor, the numbers are six digit all start with the prefix 492 with three additional numbers 492-012 to 492-045. There is a W above the part numbers. I also have 162 pictures of it at this address http;//photos.yahoo.com/bc/deccms under unidentified tractor albums 1-5. I have been searching internet sites for years and attending tractor shows trying to find one like mine Any help or leads will be checked out and will be very much appreciated. I did find a guy also in Ohio that has the exact same tractor, but his is also unidentified. Submitted by Doug Carter, from OH
