I am on my second speedo. Do wdm20's have to have a speedo that matches the clockwise direction speedo drive?

With a very few pre war exceptions. All these chronometric speedos are driven anti clock wise viewed from underneath. In other words you would have to put you electric drill in undo mode to test drive a speedo, this equates to the drive coming out of the wheel turning clockwise.....Make sense? Ron

Thanks Ron, I keep breaking speedos, but perhaps they were just worn out to start with.
