Hoover 541
You guys have a point, maybe the headlight cap is something to hang on to. And with this cap, the light appears to be built in, rather than added on. And the bulb has a screw-in base, rather than the usual bayonet style. And there is a hole right in the top center for oil. I do still have suspicions, that the motor may have been switched out at one point. I'll find out more Saturday, as Tom Anderson will be having a look at it.
And Jack, I know what you mean about the brushes, but believe it or not, yours has much more bristle left than mine!!
