In the 1930's and 1940's there wasn't any seperation for bow types except for hand shot Vs Foot shot. Arrows were often shorter than our current minimum 23" standard. In the 1940's, many arrows had hard plastic acetate vanes. Common draw weight categories were 50, 65, 80, and Unlimited. Only youth were given a 35-lb class.
There were flight rounds for what were called Roving, Target, or Hunting tackle, but there were no unique rules for these bows and no draw weight categories. What set this apart from the regular flight competitions is they had to shoot the same bows and arrows that they used in the earlier target rounds.
