Vintage Wood Shoe Trees Stretchers Wooden‎ Forms

Vintage Wooden Shoe Trees Stretchers I inherited a bunch of cool items from my grandmother but I don’t know anything about them. I thought about repurposing them for decor. I believe they are men’s but unsure of the size. This is a Left and Right and they look like the same size. They are in vintage condition- a little scratched,some paint and a nice patina. The top knobs are different- one flat and the other round but they both twist open to expand the size. I took many photos to show them open and every detail including numbers.
