Late Nord Lead 1 without "bended" chassi style - different??

[leomo]

Hello

I know there is a few late Nord Lead 1 models which does not have a bend on the right edge of the chassi but looks like a Nord Lead 2 chassi on that point.
My question is, do these later Nord Lead 1 share the same keyboard as the Nord Lead 2, or are there other updates to the internals such as DAC?
