150 MPH Speedo for Sale

@1967BarracudaGeorge the hole(circled in red in the above pic) is where the threaded stud fits through and the reset knob screws onto it. A knob is easily obtained from Classic Industries https://www.classicindustries.com/product/ma563.html
I kept the knob, and that is why I am offering to cover the shipping at this price.
Thanks @S'cuder for the clarification in the pic for him
