The Boiler Pressure Gauge indicated the steam pressure within the boiler drum. The gauge was located 15 feet above the operating floor and clearly visible from the firing aisle.

Manufacturer: The JAS Morgan Brass Manufacturing Company Ltd.

Type: Bourden Tube

Working Pressure: 400 psi

Range: 0 to 800 psi

Note: The gauge had a light in the back to make it easy to read in the dark boiler room.

It was normal for the gauge to have a brass trim up until World War II.
