Hi Papa Charlie - that is in fact the correct orientation of the motor plate. The Buffalo 15 manual shows the same configuration, and the belt aligns perfectly straight with the drive pulley on the drill. I am thinking however that the motor is not the original. What I have is a 1/2 HP Walker-Turner Driver Line motor. From what I've read so far, I've gathered that WT motors were only available on WT equipment. Someone likely swapped this motor in at some point, but it's interesting that they appear to be the same vintage.
