If going for Centurion the lower ear screw is also incorrect, should be a V-head
Ear screws shall be slotted, flat topped, countersunk and painted white.
Pretty much if you also get the strapping kit. I would suggest to ask around if someone could help you build it as that would be a great experience and actually be done faster. An experienced builder would have it finished during a weekend
That’s too bad :/ If it weren’t for huge delays in shipping I would happily paint it for him, hopefully someone nearby has the ability to help with indoor painting
That’s perfectly normal and it will close up when riveted/screwed together and then the ears cover what’s left Trimming looks good, just be sure to test-fit the ears to see if additional trimming on the back is required. I assume you’re not done with the teeth and eyes?
Ears look a bit strange but the helmet have signs of beeing a recast of the RS propmasters stunt helmet (lump on the forehead). Can’t be sure though. I would steer clear of any three part helmets (as seen above) and separate vocoder (chin detail) as there are alot better options available so I recommend checking the link Mario provided.
Good luck
