Air gunner badge

I have two of these badges, one with two lugs and one with three and to be honest they both look the same to me but a military dealer friend of mine tells me that the two lug versions are repro`s but i must admit badges aren`t my strong point but suffice to say that a badge with one of the wings missing isn`t worth anything. Having said that i will probably be proved wrong and it will sell for loads.
