This one yells "make me proper, as I'm very nice otherwise", every time I've talked to it for the past 4 years.

So, I'm on another mission. I have the correct screw when compared to the other 120 I have. From Mr. White's bible, either the "grooved straight taper" or the "flared" knob should be correct time-wise. Please correct me if that not be the case.

I'll gladly remunerate to make her happy. Please let me know if you can help, and a Happy New Year to all.
Dave
