When was the extractor strawed?

[Revolvr]

I've seen some Luger refinish work where the extractor was strawed - which looks really sharp. But according to the Luger Handbook, only extractors on models up through 1902 were strawed. The rest are said to be rust blued. The Luger Handbook is not always correct on the strawing though.

Also when blued the blueing sometimes looks different as if it is either fire blued, or perhaps the part is just more finely polished than the rest.

Thanks,
