Ireland Tax Revenu Stamp?

If it was returned to Somerset House from Dublin in 1921, I'd guess the new Irish Free State had no further use for it

That's good.

But seriously, the fire that damaged the seal would have been the IRA's attack on the Custom House on May 25, 1921. Since the truce was July, 1921, that might also explain the two-month delay in sending it back to Somerset House?

Here is where I don't know my Irish history. Would there have been little or no revenue collection over the intervening year until the creation of the Irish Free State? I don't know if anyone was "in charge" from the truce through the treaty to the creation of the new country...I could believe that no one stuck his head up to collect taxes for the crown, but I just don't know.

I'm not sure either, but proceeding on first principles ... As Income Tax was still a very small proportion of government revenues, and would have been smaller still in Ireland at the time, and Britain was a Free Trade nation, so customs duties would also have been negligible, stamp duties and excise would have been important sources of revenue.

On the other hand, by mid-1921, the writing was clearly on the wall for the British. It would have been obvious that there wasn't going to be any further need for specifically Irish duty stamps. At a guess, general, non-Irish specific revenues would have been pressed into use in the interim.

This accumulated sense of grievance against the rich in Boston may account for the explosiveness of mob action after the Stamp Act of 1765, Through this Act, the British were taxing the colonial population to pay for the French war, in which colonists had suffered to expand the British Empire. That summer, a shoemaker named Ebenezer Macintosh led a mob in destroying the house of a rich Boston merchant named Andrew Oliver. Two weeks later, the crowd turned to the home of Thomas Hutchinson, symbol of the rich elite who ruled the colonies in the name of England. They smashed up his house with axes, drank the wine in his wine cellar, and looted the house of its furniture and other objects. A report by colony officials to England said that this was part of a larger scheme in which the houses of fifteen rich people were to be destroyed, as pan of "a War of Plunder, of general levelling and taking away the Distinction of rich and poor."

Information is sketchy, but I do know there was an interim
