This is a slightly used Eaton M45, originally on a Mercedes L4 engine. I don't know the mileage but the interior is very clean, it turns over smoothly and all fasteners are undamaged.
It produces 750cc per rotation, which is an excellent size for many 1.6 liter to 2 liter 4-cylinder engines (Toyota, Nissan, Hyundai, Kia, Mitsubishi, etc.).
The original drive method is by serpentine belt, but other types can be adapted including roller chain and toothed belt.
Much of the casting shown can be cut away, re-tapped into another pattern, welded etc.
