Idk that looks like 42 but then again it could be 43, seeing as it is only a reprint of its predecessor..... Not sure, could be a hybrid.... What's it for
I have studied the differences between MK42 and MK43. The abs are quite different (the second row of abs do not contain the top squares). This is a MK42 with 2 additional pneumatic actuator under the shoulder... I don't know why, maybe in order to get a bust done correctly?
