Hmmm, Guess that's why this 1A I bought was "altered". I paid for a little education on this one. The flip-down was gone and it had been tapped for a set screw. Should've bought the Stroebel's first. I wondered why this was done after I discovered it was not factory. The stem and adjustment ring are snug. DonW
