Many years ago I was doing some plastering to a bay window in a farmhouse we were living in at the time. On ripping out the old plaster the internal corner was filled with a bundle of rolled up papers. These turned out to flyers for a musical concert in the local village hall,these had a dd/mm but no year. On handing on to the Village Hall they were later able to find out that they dated from the 1860's, so having bodgers about isn't something new!!!!
