Established in 1982 in three classes and a medal for outstanding achievement in agricultural production or in the cause of building socialist Kampuchea.
This is the third class. (Sorry, need to get an obverse/reverse scan -- shall remedy this ASAP.)
After spending 5 hours today learning how to read and write Khmer I can now inform everyone that this is "ឥស្សរិយយស ពលកម្ម".
Khmer is considerably more difficult to read and write than any other script I have worked with before. It is also very hindered by the fact that there is no single Khmer script writing application. None contain the full selection of accents needed to write correctly.
Here is an example on the wrong suspension (fine weave Friendship with brass plate).
A rather crude (even for Khmer standards), thin, painted mirrored item.
