Engine and Boiler
The triple-expansion, double-acting, reciprocating steam engine is the original, installed in 1922 when it was taken from Virginia IV (formerly Tyrus). The parts were cast in 1898 at the Heffernan Machine Works in downtown Seattle as one of two identical engines built for the Army. The first engine was assembled and installed in the US Army Quartermaster Steamer Evan Thomas. Virginia V's engine was assembled and installed in Tyrus in 1904.
