Carol Sanchez supplied this photograph from the pictures displayed in Koppl's office. Her accompanying note identifies the location as Torrance, California, and the year as 1955. She describes the work as the first 36-inch hot tap and says it took three days.

A record of the equipment

The photograph preserves a view of the large tapping machine and the piping around it. It is part of a collection of historic work photographs shared by Koppl, including images of Mr. Koppl and Melvin Coker performing hot taps.
