Yep tange made kuwys , and the aero pro. which has the same geo as a kuwy ,so that looks like the tange branded aero pro/kuwykz1? so maybe they used the same jigs and changed drop outs
my cromo burner again made by tange is exactly the same as a kuwy loop tail but with holes in the rear drop outs
who knows. but that is what i have found out as into my tange made burners
as the picture above looks like an aero pro as well as a kuwwy , but the drop outs are slightly different
