A number 4 blade is installed on the unit and an extra number 3 blade is included. The unit itself is lightly to moderately dirty and dusty throughout and could use a good cleaning. The unit shows light to moderate scratching, scuffing, general wear and paint wear throughout. The scratching and scuffing are heavier on the top right side casting throughout. Both of the blades show moderate surface rusting throughout and could use a good cleaning. The blades are very sharp and don't look like they were used much, if at all. See pictures for a better idea of condition.
