Mongolian People's Revolution 40 Years Honorary Medal.

[medals73]

Here is a document (Battushig #A43).

Two varieties are reported by Urnukh, var. 1 with larger numbers and var. 2 with smaller digits (he shows these in the picture on p. 196). Sadly, I don't have an "observed breakdown" between the two, but show only a range for the medal of 00105 to 58252.

Also a deviant Soviet-style suspension.
