I just missed on the chance to buy a C with a single tire front end. The seller said it was a C but had CA decal on it. I never got to see it before it sold, but now I'm wondering just how rare that single tire front might be. I did a search on the photo gallery and out of 90 hits for Allis Chalmers C I only found 2 with a single tire front.
Also, what is the difference between a C and a CA? How would a rank amateur like me be able to tell the difference? Thanks!
