District of Cambrai
The district of CAMBRAI had 16 post offices from 1852 to 1876.
Some numerals difficult to find, such as BUSIGNY, CARNIERES, GOUZEAUCOURT and IWUY.
The linear stamp of BUSIGNY, GOUZEAUCOURT and IWUY are rare.
A great rarity is the type 18 of SAULZOIR associated with the Gros Chiffres 6084 (ex GC of ILLKIRCH-GRAFENSTADEN). This office was opened in February 1876, and the large numerals ceased to be used at the end of March 1876.
