| N3/1231011 REF. 44 ( v (a) ) October 23rd 1911 Re Ventilation of Floorboards. Mr. Spinney 23-10-11 With reference to the question of the isolation of floorboards, will you please instruct a joiner, if possible, to get out what might be termed a thick floor-board, but what is in reality a double floorboard with a space between. This might be done quickly and without any drawing being made. X879 | ||
