Fireless "Cooker"

While I was working as a maintenance machinist in the 1970's-1980's at US Steel's Homestead Works,  I used to travel along 8th Ave in West Homestead past the world famous(at one time) Mesta Machine Co.  The Mesta plant was adjacent to the Homestead Works.  On the North end of the Mesta plant,  at the corner of the building that faced the street,  a fireless cooker was often parked there,  either taking on steam from a large steam delivery pipe that originated in the boiler house at the plant or just waiting for its next assignment.  During those years the engine was mainly used for retrieving the wood patterns used for castings.  The patterns were kept in an old wood warehouse/shed beneath the B&O bridge that came across the Mon river from the Glenwood yards.  The patterns would be loaded onto small flatcars or gondolas,  and the engine would take them into the plant to wherever they were needed.  Even after Mesta went out of business,  was reorganized as Mestek,  and became what is now WHEMCO,  that little engine sat there into the 1990's and then one day it was gone.  I could KICK MYSELF for not taking any photos when I had a chance.  If anyone knows where this engine might have ended up,  I would sure like to know.  I believe the engine number was either #6 or #7,  as both engines were still around late in the game.  Forgot to mention that these engines were made by the H K Porter Co.
