This is a letter from Robert Brown, assistant manager at the National Marginal Company in Leith, Scotland, to Robert Dunlop (b. 1869), district inspector for Commissioner of the R.I.C. Before the war middle class,a British household tended to put butter on the table, and reserve margarine for cooking purposes. But because the rations for margarine were more generous than for butter, margarine worked its way out of the kitchen and into the dining room. there was a national butter and two types of national margarine. In the letter Brown is requesting that Dunlop repays him for the expenses he paid to attend an assizes in Belfast.
