dogdaddy,
Most commonly known as "outer door window seal".
This one fits your 1950 doors
Outer door window seal, assuming they are the originals with one piece glass (no vent window).
BTW - Your previous posts indicated you asked questions about a 1949 3100 with lift bed, then a 1948 truck and looking to replace cab with a 1952 5-window. Interested to see pics of the 1950 1300 (or is it a 3100?) that you mentioned having now.

PS - I removed your duplicate post on the same topic from the General Truck Talk forum. Now that you have the part ID'd, suggest further questions on the door and window topic would be better asked in the
Paint and Body Shop forum.
