Thanks guys, glad they’re of help!
Believe it or not, the research that I and others have done on the PP2 Laser points to the Copper head on it being aligned centered with the grooves in the aluminum body, much like how the ESB's Laser is.
I actually do have the naked core template for PP2 already done up, I just haven't done any of the weathering work to that diagram just yet because its pretty intricate and I ran outa gas loll. Another member was kind enough to shoot me some better period references to use for that one though so it'll be much easier to do PP2's 1978/1979 appearance now that I have a little more than just the few crummy references I had to rely on
