I strongly doubt that you'll see any of the old Ub Iwerks cartoons on television today--this one especially. The style of these cartoons became outdated by the 1940s and most folks would be rather bored by most cartoons of the era. But what makes this one very problematic to show today are the ethnic stereotypes you see in the scout troop-- very broadly designed Chinese, Jewish and black kids. I've seen many much more offensive cartoons but I could definitely see why this couldn't be shown on television today.
In this story, each kid from the scout troop tells their scout master about the good deed they did for the day. But since Willie either has amazing adventures or he's a total liar, he naturally has the best story. In it, he tries to perform a variety of good deeds with only fair results. Finally, he becomes an uber-hero and saves a girl (almost the spitting image of Betty Boop from the Fleischer Brothers Studio) from a crazed kidnapper.
Overall, the animation is very nice (particularly the backgrounds) and story reasonably enjoyable and fun. But as I said, don't expect to find this one on TV...and I was able to find it at archive.org.
