Crouching at around 6" tall is this vintage windup Ultraman Jack from famed tin toy manufacturer, Trade Mark Modern Toys (aka Masudaya Modern Toys). Unfortunately, the winding mechanism is missing (see photos). However, this is a great representation of antique sofubi and makes a stunning display piece. Arms and neck are articulated.
