1901 part envelope registered from Paonta to Nahan franked with two copies of the 1885-96 3p orange Type B and 2 annas carmine cancelled "PAONTA / SIRMOOR STATE 28 OC 01" squared circle cancel with "SIRMOOR STATE / NAHAN 29 OC 01" delivery cds on reverse. Internal franked Sirmoor covers are virtually unobtainable because the Maharaja of Sirmoor had issued strict orders to have the stamps removed from all articles of mail prior to delivery. Only a handful of such Sirmoor covers exist, the majority of franked Sirmoor covers are combination covers addressed to areas outside Sirmoor State. BPA certificate
