hello- ibought used crank but now not sure if it's for model A-does not lock in crank nut well and slips out easily. the pins are oval-should they be round? i';ve enclosed a picure attachment---i put tape on the pin to better show the shape of the pins. is this model A crank? thanks

Measurements with the pic's of the whole crank would be a game changer in determining if it is Model A or not. Many originals have alot of wear on the lugs. Rod
 
Also check the 4 teeth on the ratchet bolt that the crank engages. Many of them have been used a lot and have been so badly worn they don't hold the crank lugs too well.
 
thank you -will check teeth-also took measurements and found the diam of crank is .75" the pin is 3/16" thickness and is 3/8 " in breadth-------i don't think it was a round pin that has ovalled out.

i guess the last ques i have is: is the crank pin to a model A round, if so this is not a model A crank. thank you

Thank you all I am most thankful I did not know that cranks had so many variations. Thank you especially for the list of cranks, I had no idea
