LMAO....that spider might help chew those helmets into shape!
That adjustable visor style helmet has a fairly well defined step, the Revell molding has it as a big bump running all around the helmet from ear to ear, and it has no visible end points.
I've looked on the web for a good close up and worked it as best I can. If you look closely, you can see the stepped ridge I've attempted to cut in, just either side of the locking knob at the top.
If anyone has a good close up of that, or the rest of the helmet, please post a shot or two. Also, as I've noted from other 1/32 figures, those guys are the wrong size, about 1/35 the scale.
They are having a terrible time with that Wolf spider, and I think the little guy got eaten. So now I know what the carpet monster actually looks like....lol...
