Who made this medal?

Trying to find the name of the company that minted this medal from 1937.   And any other interesting info.

U.S. Constitution Sesquicentennial   in bronze   1.5" in diameter  The edge is very thin so there is no marking.

It's a watch fob issued by the U.S. Constitution Sesquicentennial Commission. I can't find any examples online but here is something similar:
