Thanks for the input guys , the stitching does look very suspect i know , it was the background colour that struck me as being odd , as all the other 487th patches i have seen are a bright blue colour , also they are all fully embroidered and not a sort of "multi" piece construction as this one is
I have patches here at home that show the same style of stitching on the back ,i am not holding out that it is original as the seller is a well known dealer . It was bought as a "repro" . Just thought id let you guys have a shuffty at it to hear your thoughts
