The nose guns, at least i assume that's what they are, were halves
from aircraft external fuel tanks, thankfully i had 4 that matched.
The muzzels were kinda right shaped bits i found in some Japanese robot thingy kit.
The missile tubes were a single item turned up out of resin after drilling out the holes,
saved trying to do it after the cone shaping i can tell ya.
Just moulded and cast 2 off, that was that job delt with.
