It’s the little things that take some time. So many small items that have to be done. This is one of them. I’m replacing the 70 year old airspeed with a new True Airspeed and I had to get the dial rescreened with the correct ranges. I also changed the new one over to MPH from Knots. I sent it to Precision Dial and they did a great job. I will send other dials there to get updated.

Also, the range markings are painted on the glass in the old Indicator and the glass has rotated, throwing them off  and it was not complete with all the marking needed.
