The Masca Contra Gazelor md. 58 is a gas mask that was issued to the military of the Socialist Republic of Romania. It is almost identical to the md. 52. The only differences being that the md. 58 has an exhalation valve added to it and is made of higher quality rubber.

The example pictured is missing its bag. The filter is dated 1974.
