That is of course a distinct possibility that the extractor slot was staked after it left the factory. There is no screw hole present in the rib extension so without the stake the extractor would simply pull out.
On none of mine though will the extractor pull out in removing shells. They either have to have a block removed, forend removed or an intentional effort made to spring the extractor out. These all require the gun to be disassembled.
I do not have as many as some collectors but do have from a low number of the 10,515 up to 73,338/73342 with the rest scattered between. I only have the two mentioned which are pre large hook. I have the E grade & two G's mentioned, then an FE @ #38,025. The rest are H grades & all of my H's number in the 40K range & up. Have these with & without the 1907 patent date so a fair assortment from different eras.
