I didn't fail anything, I was answering the question asked without any assumptions. He asked about pre and post. The "New CLassic M70 CRF" was the third variation.
Of course we could go further into details about the 3 design variations of the Pre64 but again that wasn't the question. And we could talk about the M54 which the M70 is really and improved version of. But now we are really far flung, something I was avoiding and why I only addressed the question asked, which is always a good policy. If the poster wants to learn more they can ask for more info if they desired.
