Another Union Supply Store at Wynn, PA, a coke patch built in the 1880s. One of the earliest operators at Wynn was J. W. Moore & Company. Later H.C. Frick Coke Co. added Wynn to their coke empire. Union Supply Company was the retail subsidiary of H.C. Frick Coal & Coke Co., which itself was later a subsidiary of US Steel.
A watering hose for quenching coke left in one of the Wynn coke ovens, which are some of the best preserved in Fayette County. The coal mine at Wynn was closed in 1926, but these ovens were kept in blast by the Ruane Coal and Coke Co. into the mid 1950s.
