Vintage Military Pin Roadrunner 40/8 Unit

Description

The only information I can find on this pin is below which I believe is correct but not sure....
The official emblem of the 40 & 8. The triangular shape suggests Veterans who served in the air, on land and at sea.
The organization (also known as "La Société") can trace its roots back to 1920, when Joseph W. Breen and 15 other members of the
American Legion
, who were veterans of
World War 1
, came together and founded it as an honor society for certain Legion members. They envisioned a new and different level of elite membership and camaraderie for leaders of the American Legion.
The title "40 & 8" comes from the
box cars
that were used to transport troops to the front in
France
. Each car had the emblem 40/8 stenciled on the sides, which meant that it could carry 40 men or 8 horses. These cars were known as
forth and eights
. They were seen by the troops as a miserable way to travel, and the new organization was thus called the 40 & 8 in an attempt to make some light of the common misery they had all shared.
In 1929 it was described as "the fun-making organization of the
American Legion
In 1959 the 40 & 8 became independent of the
American Legion
, although still required membership in the
American Legion
. In 2008 the 40 & 8 dropped the membership requirement in the
American Legion
