Following on from this earlier post, I have finally completed the mortar and it's crew. Though clad in uniforms from WW2 - or rather the Great Patriotic War - I carried out a 'paint conversion' exercise and painted them in the camo scheme introduced in the 1970s. As usual with toys in this scale (1/35) I have gone for a 'toy soldier' finish. They look OK to me.
These two photos show the mortar with 3 crew figures and mounted on a 4-inch square steel base as used in my Little Cold Wars game.
