I have other  TRANSPORT/SPORT BADGES on ebay, so have a look at my 'Seller's Other items'.

Condition as seen.

Pulled the following Text from AI : 

A "1945 De Havilland Aircraft Company war workers victory thanks badge" is a specific type of commemorative badge, likely issued to employees after World War II to thank them for their service to the company's wartime production efforts. These badges are often in the form of a lightweight alloy disc and are considered scarce collectibles, not to be confused with company logo badges or specific military aircraft badges. 
What it is: 

    A commemorative badge from the De Havilland Aircraft Company.
    It was issued in 1945 to thank war workers at the end of the war.
    The badge is a lightweight alloy disc. 

What it is not:

    It is not the company's main logo badge, which features a chromium-plated aircraft with "D" and "H" on the wings. 

It is not an official military badge, though some military aircraft like the Mosquito had their own associated badges.
