There maybe another way to tell.Only thing is the engine needs to come off the base and under the engine near where it bolts on there is a number cast into the base.Now I can't remember what the VC-125 Mark I had but the Mark II has a 4 cast into it.If it's a 1 I believe it would be a VC-160 Mark II.I don't know what these numbers stand for,but from what I have seen they are slightly different from each other.Don't know why or what it means.
