cover 1933 (Mar.) mourning XU5 from Portuguese India to P. & O. "S. Chetral" Singapore (on reverse) at 6r., bearing Straits Settlements Postage Due 1c., 4c. and 10c. on face cancelled by "CHARGE NOT COLLECTED/FRESH LABEL REQUIRED" cachet and two Singapore c.d.s.; redirected to Hong Kong and with Postage Due 1c., 6c. and 10c. marginal pair applied to reverse on arrival. A few faults though a very scarce and unusual "double" Postage Due usage. Photo.
