Map of Brunei 1749
This 1749 map shows Brunei (circled red) as Borneo to differentiate it from the Island of Borneo (Isle de Borneo). Brunei was generally known as Proper Borneo in many maps around those periods. The more the mappers know of a place, the more detailed the maps are for that particular place. Hence Borneo is properly shown together with Labuan Island just off the coast of Brunei. Tanjung Baram was known but someone would have to tell me what happened to Bacasa or Canciran both very near Brunei in this map.
