Black and Decker or Wolf drill (Hanworth RG12)

Hi, I'm looking for a Black and Decker or Wolf mains powered "pistol" drill. Similar to the ones in the pictures. I've acquired a B and D drill press stand that holds a drill body by clamping around a collar (arrow in photo pointing to the collar). Chuck size not too important. 3/8 or 1/2 inch. I need to accurately (vertically) drill some holes in wood
