Good evening I want to say a man by the name Tom, Who is a local to Chicagoland who is an AC Gilbert historical member was at the Convention at the Holiday Inn Elk Grove Village, a few years back
He had one of these and he had parts. I almost purchased it,
You may want to go through the directory and look for someone by the name of Tom and reach out to him. I don’t know if this will help you out or not but I figured I try to help.
