French, Customs Seal, 185

I, 185 Seal, Image by StuE, Found by Allsopp.
Found in Staffs area.

Small seal with deep circular indentation on both sides, one containing the stylised letter I, the other the number 185.
From a distinctive group of seals with various numbers on the reverse. Some have CONTRIBUTIONS around the inner raised edge and possibly IND - an abbreviation of Indirect to give 'Contributions Indirectes' - indirect taxes (French). "Taxes can be divided into direct taxes (taxes on income or property), and indirect taxes (taxes on alcohol and tobacco)." From 'France as a superpower 1700 - 1715'
The style of the I (resembling a J) matches that seen on a letter envelope stamped Minister des Finances Administration des Contributions Indirectes dated 20/12/1834. Delcampe - Ministère des finances/administration des contributions indirectes/lettre pour le prefet d'Agen.
