Vintage Marble Swirl Slag Glass Gear Shift Knob Ford Harley Indian 5/16" thread

Description

Up for sale is a real nice vintage Glass Marble Swirl Slag Glass Gear Shift Knob.  This will fit early Ford vehicles like the 1928 - 1931 Model A or 1932 through 1939 Fords that have a 5/16" UNF thread at the end of the gear shift lever.  It would likely also fit vintage motorcycles like an early Indian that have the same thread on the gear shift lever.
The knob is just under 2" in diameter at it's widest point.  The knob is in excellent used condition.  There are no chips or damage on the glass surface.  The threads are perfect.
I will ship the knob through USPS Priority Mail with the Delivery confirmation.  The box is 8" x 6" x 3" and weighs under 1 lb.
