Hey Mick, bin a while mate, you been hiding? I Have

The Holes, after having a lil poke around, Ive discovered these holes are indeed incorrect in the format shown above by many skinners including myself..oops

The holes appear on the Odd Late G4/5 late G6/AS to G10 & G14s as far as current information suggests,although it seems to be hit & miss, no one model displays the holes throughout its production, still dont know what theyre for though, Ive tried to identify other differences between models with & without holes which may explain their reason for being,Eg: theatre of ops, fuel tank position, type & alterations made,cockpit variants, not really come up with anything conclusive other than theyre possibly venting/overspill/holed tank ports for the fuel tank behind the pilot, possibly their purpose is to offload excess fuel caught in the fuselage void when a fuel tank has been compromised & luckily doesnt Ignite, im assuming theres a delay between holing the tank and it actually self sealing?
Theyre usually found in the positions and size as per example below, hope it helps old chap
