Old bottles

I have a collection of old bottles that I have found over the years on the hillsides around Hong Kong island.  The Watsons bottles were found on the hillside behind the Governor's summer mansion on the Peak (before the slopes were concreted).  The flat bottomed torpedo bottle (Aquarius) was found in Tai Tam.  Can anyone date this one?

Any other bottle collectors out there who can give me any information on them, i.e. age, use.

Have also included a Dutch gin bottle found near the Matilda Hospital on the peak.  From research this is dated late 1880s and the company originates from African Dutch colonies!
