Walther P-38 Decocker

I have a postwar (1958) P-38 and I have a question regarding the decocker mechanism, or lack there of. Apparently, mine doesn't work properly.
On another board, I found a schematic (Numrich) which identified all the parts, but none were identified as having to do with the decocker.

Could someone please identify the internal part(s) that are involved?

On Gun Parts Corp (Numrich) the decocker parts are.......

The safety, part 14
The hammer lowering lever (de-cock lever) part 17.
The sear, part 20.

The way the P-38 safety operates is.....
When the safety is turned down the firing pin is locked.

The safety presses down on the hammer lowering lever part 17.
This is on the left side of the frame beside the hammer.

The hammer lowering lever presses the sear UPWARD, which releases the hammer to drop on the firing pin.

With the grips off you can see the operation of the hammer lowering lever.
This looks like it should press the sear DOWN, but in fact the sloped lug on the lever pushes the sear UPWARD to release the hammer.

If the action of this is sticky or not working, the lug on the lever may be worn or the area it pushes against on the sear many be worn.
If the lever is worn, just cut to the chase and replace it. Stoning it never seems to work out well.
