OXYLON Mouthpiece & Hoses

	Mouthpiece looking into the hose connection. The inner white sleeve is rotated by the knob to the right. The silver rings expand to seal the white sleeve to the housing.  A unique feature is a drain hole so positioned that when the sleeve is rotated to close the mouthpiece, water in the outer mouthpiece can be expelled.  Didn't have a close-up lens, thus blurred image.
	One hose connected tot he mouthpiece (scale in inches).
