Old Industrial Combination Swage block:
This is a fairly primitive block and fairly well designed with only one weak corner.
The two curves at the top are catenaries created by bending a thin piece of wood or drawing by hand rather than drawing them with a compass.
These large curves and the shallow bowl depression make this a combination block rather than a strict industrial block.
New evidence indicates that this block may be a II&B Vulcan brand no. 4 or 4½
