Default Re: Pulley casting number

I have an 8BA pulley that looks similar to that shown except it has 3 reinforcing webs on the backside. One web is on each spoke. Both are narrow belt pulleys. Large pulley is 6 in. dia. Smaller pulley is 5 and 1/4. Each measurement was taken at front of each sheave. Crank hole is a tiny bit less than 1 5/16.
