Insight into how blocks were cast in 1969

[bergy]

The actual block casting is only about 3 1/2 inches long. It was mounted to a plaque with the dates of my service at Tonawanda. The core/mold assembly was actually a gag gift that they made in the pattern shop. We had a few problems with the core assemblies mis-aligning in the mold. The inscription reads "Parallelogram Effect" - the little barrel cores actually don't sit straight in the mold on purpose (hard to see in the picture).
