The Historic Compass of Shanti Museum is a 1552 years old piece made by Shanti Museum, a engineer living in Ulaanbaatar.
Considering its age and the quality of the work, people consider it of considerable value.
It is engraved with asian patterns and some symbols pertaining to Jainism.
This piece doesn't exist, but as a legend. It is said that in the year 454, Nomolun Museum, the owner, made use of it in Delhi to empower the Museum family. Now it is lost, or broken, we will never know.
