In an artical I once read regarding a build of a Fw-190, The builder had mentioned using a "Dry-Transfer" decal on the struts of his aircraft to depict the real aluminum sheet with the "Warning" lable or the "specs" of an item that this "plack" is attached to...

I have done a search for dry transfers but could not find a sole sheet that would have the small, black, rectangle decal for the struts mentioned in That artical......

Does anyone have any idea has to who makes them and how to get a hold of them....?
