The trim tab indicator was rebuilt from scratch, I had no parts. There are a couple of drawings on the F19 manual, but my main source was Robert Lees implementation described at http://www.taylorcraft.org.uk/trim-system-new.htm
To realize the text and the drawings I made negatives in vinyl using a Cameo Silhouette cutter.
