Vtg Polyester Mens REPP Necktie Brown Beige Orange Diagonal Striped EUC READ

Mystery label and Coat of Arms? This vintage 100% polyester men's necktie has a label on the back without a manufacturer and a small metal clasp with a coat of arms with the letters A & C and a knight's helmet. This little clasp holds the back of the tie together. I have researched several places but cannot identify this label. This tie measures 3"×54" It is a REPP (textured materia) in brown, beige, orange and thin blue stripes running in a diagonal pattern. In excellent used vintage condition.
