Question 11 Third valve slide waterkey

Different Olds models used a different style of water key (spit valve) on the third valve slide. Please note this is not a question about the water key on the main tuning slide, but about the water key on the smaller third valve slide.

The water key is operated on the bottom side of the slide. (Ambassador models)

The water key is operated from the top side of the slide

There is no water key on the third valve slide (some cornets and flugelhorns)
