difference between Brevis35 Rev2, MP.1 and MP2 ?

[Ibrahim Alkhulaifi]

Hi all,

I just wanted to know the difference between Brevis35 rev2 and MP.1 and MP.2
I'm looking to buy a used Brevis35 and I got confused and didn't know what to buy.
Which of them came first? I know that the latest is the Brevis MP.2.

I this might be a silly question but am a Novice to the Brevis35.
