The park is Stenton Park and was littered with tiny ziplock plastic bags when I was there taking pictures of the old factory in 1986!! Not many Germans left in the Germantown section of Philadelphia. The original gun factory is the part with the grey roof touched by the word Traffic. That factory was built in late 1903 for Philadelphia Arms Co. The original A.H. Fox Gun Co. factory was at the corner of Wayne & Bristol Streets, and was a vacant lot when I was there. AHFGCo. moved into the factory at North 18th & Windrim in late 1906. The part with the black roof was pictured on the cover of an early 1930s Fox Co. fishing reel catalogue.
Here are some pictures of the factory from 1913 when the railroad was remodeling the grade thru the area --
