Years ago I had a Columbia AH, first style. The analyzing reproducer
has a pin on the back side which fits in a hole in the traveling arm to set
the needle at the correct angle to playing records. I think it had a thumb
screw to hold the needle in place. I don't think the Columbia name was
behind the diaphragm. It may have had a patent date; I can't remember.
This inportant thing is the pin stoset the angle for playing.
