IRISH Entire 1789 - CASHELL (Whitney 5/10) Rarer

One for the Irish collector.
Entire written in 1789 - momentous year in Europe!
Entire is quite delicate: addressed to Revd Lambert with faded but still clear CASHELL town mark. This is of uniform height and I calculate this as Whitney 5/10 which is rated (years ago) at £20.
Good offer......don't miss out.
