BEING RESEARCHED 1930s FTA (Freight Transport Association?) Pin NOT FOR SALE UNTIL IDed

This is an unidentified 1930s pin, most likely for a transportation association. The letters FTA are at the top of the pin in Deco script, and could stand for Freight Transport Association, or something similar. The pin is gold-filled and shows symbols for rail, steam and air transportation.

Circa 1930s.

Approximately 9/16" in height and 1" in width.

Gold-filled.

Horizontal pin with drop-in locking catch.

This is from an unidentified collection which we will be listing more of over the next few months. Item will not be sold until it is identified. LAAE?X7/11

7 (Very Fine): The pin shows some small areas of light to moderate wear and tarnish.

As with all my artifacts, this piece is guaranteed to be original, as described.
