No, Pre-V watches didn't have that engraving on the movement. But then, Pre-V and Pre-A/A-D series watches had steel case backs, so you wouldn't be able to see it anyway.
Honestly, the finish of the movement is so far off from the gen SOPROD decorated Panerai movements that anyone who knows that the font is off, will know it is a rep, regardless.
If it bothers you that much, get an auto PAM or a Pre-A/A-D series manual with the solid case back.
