About 6 monthes before the finish of the restoration of #5 in Deloras, CO. I was fortunate enough to get a tour of the workshop. The most scary thing I saw was the oringinal air hose connection. Air hose connections are usually factory made and heavily designed pieces. The goose connection was standard rubber hose connected to the metal tubing with wrapped tie wire. It was a very neat job but..but (OMG!!). These things were really cobbled together. These contraptions were held together by dedicated people and whatever was handy.
