Yes, originally and traditionally a track stem going way back, this basic design goes back to the beginning of Paramounts in the 30's for Schwinn.
Most of the other major manufacturers had something similar probably well before them.
It is often referred to as a Major Taylor stem. We are fairly certain this one is original to this bike.
Richard Schwinn says many people used them on road bikes as well.
