Sample Glyph files using components? To learn from

Are there any sample .glyph files to learn from?

Following this tutorial of smart components, it shows _tail.Q and ae, and would like to learn how to build other glyphs for other letters such as w.

The tutorial shows that w was made from v and an additional part, would like to know what names were used for its parts, and see examples of how other letters can be constructed.
