I owned one of their later light grey/blue lathes, but I've seen a couple build threads involving the older green versions.

Easy way to tell, is you should be able to stick your hand up under the saddle and feel the X screw. You might be able to get your head at an angle to look at it, or take a photo of it with a camera if you really want to see it.
The Z axis, if you take one of the securing screws out one end of a telescopic cover, you'll be able to slide the cover back so you can see the screw.
