Colver Skysail & vario stuff

Every once in a while I dig through my old HG boxes and files and I see things that I didn't remember were there. So I decided to participate in this HG history section by starting this section to deposit copies of drawings or photos pertaining to the Skysail and Variometer, my two contributions to what with the passage of time became part of the sports history.
Some items may already be in other sections of the US Hawks forum but this will eventually be a concentration of the historical stuff pertaining to those two original designs.
The first item deposited here, I stumbled across today, is a copy of a three view drawing I made when the Skysail was one year old. I did not remember that I had made this drawing.
As noted on the drawing it is scale 1 foot = 0,2". The background grid is 0.2" squares.
