She definitely has a huge burr in the form of the locating finger on the hook base being broken off.

I have dealt with this exact problem when I serviced a 301 that had had the babbinn case base replaced by one from a 221.
I just disassembled the 301 - the part number on the Hook base is 170166. You are correct! (Not that I doubted you.
)
I did know that the piece with the 2 springs on it was different, as well as the throat plate (because it has screw holes for the springs in a different spot) but I didn't realise the finger was different too, but looking at them side by side, yes, they are a little different.
I wonder how many other parts are listed wrong on all of these sites then
I wonder if the "replacement" was the 301 version and the longer finger is "OK" on the featherweight? I just don't know if I feel like disassembling both to find out...
