This is a Libman dustpan, model 906, 10 inch. Libman sets its fibres into the block under tension rather than gluing them to a backing pad, which is why the head keeps its shape instead of splaying after a few months of use.
Catching what the broom moves, without the lip that leaves a line behind.
The Libman Company has made cleaning tools in Arcola, Illinois since 1896, and states that most of its products are made in the USA with US and globally sourced materials.
