Jerry Burney stated above that the firing pin was changed at some point, possibly by Mauser. it is highly likely this extractor was part of a Mauser overhaul..This was a part that Mauser beefed up on pistols when they started production and it wouldn't surprise me to see these changed as well. The extractor locking hook on DWM pistols was very dainty and broke fairly often I suspect. I have broken one on an Artillery shooter. Mauser made them much stronger and the Swiss completely closed this hook into an arm with a hole in it. So it was obvious to the Germans that it was a weak point. The only way to see is to take out the extractor..Not difficult at all but not something the average collector does either..
