By now, it should be obvious that there very little left of the original SPFX casting. It isn't just covered in putty. Somewhere along the line, it became obvious to me that the problem was with the 'squishing'. When you push one area in , somewhere else must go out. Looking down on the dome, with the 'widows peak' being 12 o'clock, the hemet is squished in at 2 o'clock and 8 o'clock.
I am aware that the original helmets are narrower at these points, but this casting sagged inward at this point even further.
Hence.. It is extended out at about 10:30 and 4:30. I have sanded and re-glassed these areas extensively trying to slim that 2 o'clock profile. But the helmet still looks a bit 'wide' when viewed from this angle.
NOTE: I determined after this pic, that I had built out the 'grey' cheek bone too much and if it was where it should be, the helmet would be turned more toward you and the leading edge of the far dome skirt would be more visible as would the far side of the forehead on the dome.
I lost the early pics of this angle in my computer crash, but it was a lot worse. This is about as good as it is going to get without a grinder, a shop, and some serious reglassing work. but I tried....
