The partner that I was aware of was Peter Guild, I thought he had the Z?. He and Bob Olsen developed MSR into Pro-Motor Engineering. They went on to develop one the first motor leasing companies in Nascar. They are still in business in NC. Some of the old staff that I remember included Gary Roden,Rick Gerardi,Dave Pedigrou. I recall they even had a women named Birdie that worked the counter in the Des Plaines location back in the mid-70's
