What you might need to do, if function is not required, is to get a single lamp from somebody, and 3D print some pieces to assemble into a facsimile. These lamps were not off-the-shelf items, but were either made internally by IBM or made for them. They were used on a wide range of IBM machinery from that time period. We used to have an ashtray on the CPU console with a dozen or more of them, so the operators could replace them when they burned out. Obviously, millions of burned out ones were thrown out. Jon
