Need connecting rod for Sanborn type ''143'' air...

Question

I need a connecting rod for my Sanborn type ''143'' air compressor pump. It seems it's an obsolete part as the Company was taken over by Coleman and the pump was manufactured by E.L. Smith (now Stellar Industries). The rod # is 047-0008. I am hoping that someone either has a NOS or used rod, but so far have been unable to locate one. Any ideas?
