Looks like LT all the way, to me.
AG100s had all of those extra protection bars everywhere, a fatter tank, alloy fork leg lowers.
Pretty sure that side-stand foot is an add-on.
The AG has two airboxes - one just behind the fuel tap, and a second in the 'normal' spot. An AT1 has just the one, behind the fuel tap. Don't know what an LT should have - but I don't think its what's pictured.
