About Soviet Mortar

[xiaofan]

Found this photo on line (http://www.gazeta.voenmeh.ru/n1-2-2013.pdf), and the mortar in the photo looks like too big to be a 120mm one so I guess is a 160mm mortar, also it does not look like a breech Loading mortar.

Can any one kind enough give some information and/or photo about this mortar?

As far as I can tell, it is a 120mm mortar, PM-38 or PM-43.

Yes, it is a common 120 mm regimental mortar, most probably the PM-38. The thing looking like a muzzle brake is a double loading safety.
