Porter-Cable 840 Cordless Drill

I thought I had Norm's P-C cordless drill inventory sorted out. Then I discovered there was a fourth drill that showed up for a while in the '90s. It looks somewhat like the 862 (and I called it that) but has a very distinctive rear end. It's quite flat—unlike the rounded edges of the 862 and 98xx series—and there's a concentric boss back there, too—equally flat and a little over half the diameter of the body. There are also no vents. Like the 862, it was discontinued long before I got this project underway. I found the model number from a parts list (it's also referred to as a 9840—P-C sometimes uses a preceding “9” to denote kits, although not always).

Well, not ebay, but some other for sale site finally produced an image. It was in a case with charger and battery, which I cropped out, which is why the edges are a little fuzzy. Below it is a screen shot featuring the rear end from episode 911, almost its last appearance.
