Model A or B. Measure the diameter on the inside that rides on the crank. A would be 1.625", B 1.875" Neither are worth a lot because new rods are being made. B rods $25 ea. at the most, A maybe half that?
OK will get them checked and advised. Someone said $25 but in Brattons and Snyders they are listed for $97 - $99 each
