gearshift knob

[Tom Endy]

I welcome comments from the old timers. During the restoration of my grandson's 1930 Tudor we found that the gearshift lever had an extension with a mushroom knob attached to a short extension. I know about mushroom gearshift knobs, but what is the story on the extension? The assembly appears to be era. Was this for extra tall people? I was able to unscrew the extension from the knob as it has an internal thread at each end. The knob itself has a short threaded stud inserted. It appears to be imbedded in the knob, not screwed in.

Original mushroom knobs do not have edge serrations or ridges as yours does, must be aftermarket or somebody's special adoption. Original mushrooms also have a shorter underside curve, they are more "top heavy"
