Does anyone have the details of standard section Z 15/24 “aluminium” ?.
This is believed to have been used from the 1920’s onwards.
According to the drawing on which it is called for, it was used for trailing edges etc.
Looking at the drawing, it would appear to be a V section, with inward facing flanges on the ends of the V arms.
