This heavy mortar was originaly made to go with my 15mm orcs, but as normal with orcs they havehuge over powerful weapons, This mortar will do for most scales from 15mm depending on whatyou are looking for. Itis a double mortar with breechloading,which can be glued open orclosed. Itis a very easy7 piece kit. To give you an idea of the size. It stands 23mm high andthe measurement of the gap at the base is 32mm long.
