This is the first LX to come with a suction ejector already installed as standard equipment. Look closely at the photo of the ejector knob -- you'll see it's a metal knob inset into a metal flange. This is very early and pretty rare. I'd love to get this myself but have one already.
The machine is in very good condition; the cord winder has the original Belden plug and there's the original hose. It's a bit faded but try finding on in ANY condition today...
