The shovel in the photo appears to be an Erie B-2 crawler
steam shovel. In addition to boarding up the windows and
doors, the boiler stack has been removed for shipping. The
Erie Steam Shovel Company of Erie, Pennsylvania manufactured
this model in the 1920s. In 1927 Erie and Bucyrus of South
Milwaukee, Wisconsin merged forming Bucyrus Erie. Bucyrus
is now part of Caterpillar.
