This wing is by far, the ugliest, ill-proportioned French made wing I have ever seen. I normally don't like to discuss what I paid for an item, but in this case, I will divulge...$39.95 on ebay. At first glance with the poor photos provided, it was easy to see why I was the only bidder. But once I cleaned up and enlarged the seller's photos, I saw a very characteristic element that put any concerns to rest.
The construction of this wing is just like the example on my Wingate uniform. His uniform was tailored in Tours, France, down the road from Issoudun where he was an instructor. The incorporation of tiny silver sequin-like washers forming the "feathers" on each wing, seems to be unique to a tailor in Tours.
This wing is large, measuring 3 7/16 in. wide. Including the washers, I count 6 types of bullion. What is most perplexing is the color, it appears to be in gold. Additionally, the shield appears to have been constructed around the 'US' collar insignia - which is firmly embedded in the thread work. I have placed the ugly duckling wing above the Wingate example for comparison.
