This is a Snap-on impact wrench. The model number is MG325, and I believe it was a 90th-anniversary model. I think there was a limited-edition design boot, but it was in poor condition, so I will include it if you wish. The rubber part on top is slightly peeling. Please check the images. The socket size is 3/8. The impact function does not work when a load is applied, so please purchase it on the assumption that it needs an overhaul. Price is negotiable. Type: Air Tool Other Tools: Impact Wrench Type: For Bicycle
