I am going to try and post a picture of this model t crank. From the markings on it, what do we know it might be? It has Ford, a Indiana teep with a F in he upside down V, and perhaps two A's on that side.

Ford mfg. Model T crank, later version with the more rectangular throws. The 'AA' is the improved steel formula. These appeared about 1924. Later, in 1927 the material was changed to 'EE' marked, and these cranks appear to have the better steel formula for longer lasting. The other markings are some type of forging references.
