Used A/B Multi Hole gear case housing that has been shaved on both sides of the torpedo along with a bushed coned nut shaped to fit the contour of the case.  Has studs, fill screw and vent screw.  Threads are good on both the housing and the nut.  Has nicks in polished surface.  Still has the driveshaft needle bearing but not sure of the condition of the bearing.  Looks to be a nice clean case.
