Re "Dutch petroleum installations on Borneo"........... historically, the most northerly of those installations were on the island of Tarakan, which is not on this map. The others were around Balikpapan, which is much further to the south. The part of Borneo included with this map was British Borneo and the most northely oil installations there were around Miri (not on this map either).
While struggling with my East Java map I started work on two Borneo maps... so far only made map_c, map_t and map_h, nothing more. Originally I wanted to include Davao and Jolo on the East Borneo map, but I'm not sure that such a large map would even load................
