Welcome mate!
Re an accurate Lanc...the later Airfix kits have the most accurate outline (In my opinion), though the technology is of course outdated (scratchbuilding and superdetailing required for an accurate kit). The new tool Revell and Hasegawa's are of course beautiful in detail, though each has it's mistakes, some major, some minor.
There are threads on these kits around the forum if you want more details - comments by Ian (Ian Lanc) and Terry (Airframes) are especially worth paying attention to!
