German helmet chin strap by ftb 1943

In my opinion an original, genuine, full length chin strap for a German World War Two helmet in good condition. Steel buckle in green color. No repairs. Light worn piece. Maker marked on the other tip by ftb (three letter code for the firm 'Landeslieferungsgenossschaft für das Tapezier-, Sattler-, Polsterer- u. Dekorateurhandwerk Baden e.G.m.b.H, Sitz Karlsruhe (Baden)) dated 1943.
