Here is a Hungarian AKM 7.62×39 Firearm Manual
Hungary was one of the first countries besides the Soviet Union to start manufacturing AK rifles. Hungarian specialists (along with Chinese and Czechoslovakian ones) traveled to the Soviet Union in 1953 to learn the manufacturing technology of the rifles. The first Hungarian AKs were mass produced in 1959-1960.
The easiest way to identify the Hungarian AKs is to look at the fire selector markings on right side of the receiver.
On Hungarian AKs, it is stamped “1” for single shot position and there is an infinity symbol (∞) indicating the full-auto position of the safety selector lever. Also, on the rear sight of Hungarian AKs, there is a letter “A” on the rearmost notch which is normally equal to 300-meter sight setting.
Lastly, AKs made by this country have a serial number system consisting of one or two letters followed by 4 or 5 digits.Hungarian AKM 762×39
