Hao Wang Construction Sets

Hao Wang is a Meccano-like construction system. Many of the models come from old Meccano manuals. The manuals are all in Chinese. The parts are similar to Alpha(1) and it is thought that it may precede it. It was made in China in the late 1950s and perhaps into the 1960s.
