I found this impact driver from Japan recycle shop without a battery. It looks very old, but I believe that it will work after the restoration. I rebuild new battery with lithium cells 18650 and BMS 3S20A. It's designed to be different from the impact driver I've ever had, It's a little tricky to get it in pieces. You can see it in detail in the video. The problems with this tool are dirty, old grease, old paint, no battery, and no charger.
