As far as I know, he miniature pins are to be worn on a dress jacket and fall under 'military uniforms,' i.e.- not for civilian use. However, if I were to, I dunno, make up a kilt with the pleats matching the colors of a military ribbon that meant a lot to me, that would be fine.

So you could use a reproduction of it, somehow altered hopefully, but not the pin itself. It's just so they're different they don't get mistaken for 'real' military stuff being treated with disrespect.

I'd be a little leery of using the wings exact duplicate without something to show they're totally unofficial, like putting them on a shield or along a plain bar or something. putting the wings along the blade of a sword kiltpin would do the trick, or using them as the 'handguard' between the hilt and the blade would look pretty cool, too.
