Good afternoon my name is Jim and I recently acquired a 1952 or 1953 W4. This is my first bigger tractor that I have owned. I mainly have Wheel Horse tractors but could not pass this one up. Anyhow so I am having a difficult time identifying the exact year due the serial plate being worn. The two numbers in the middle are super hard to read. Does anyone know of any tips? I tried a little oil pencil and paper and cant think of anything else. I think Im reading WBH 31381 WI but in my research I do not see that serial listed anywhere. Also what I find odd well it may not be odd it just may be my lack of knowledge on these machines. I am learning though. The W4 in what I have read came with the 152 cubic inch engine. Now on the W4 I have the block is stamped with C-169. So Im assuming the engine was possibly replaced? I am not sure as I am learning. But any help and guidance is greatly appreciate. I just need to pointed in the right direction. Thank you.
