In Case You're Wondering: What Is a Trunnion?

From Wikipedia.

Since I have been mentioning trunnions in the last several posts, I decided to look it up to be sure what they were.  It was as I had figured.

A cannon's trunnion is the part that protrudes from the barrel near the rear which rests on the carriage and is used to pivot the cannon up and down.
