It's likely from a Curtiss JN4D with an OX5 engine. It's a so called "toothpick" design. The toothpick was much less expensive to manufacture than the early scimitar shaped propellers. With trainers like the Jenny, propellers were destroyed frequently, and frequently a number of spares would be kept around because of that, many of which became obsolete and got picked up as display items instead. Here's another example of one.

There was a lot of variation in how they were stamped.
