I personally wouldn’t scale anythin up from a model. It is also bad practice to scale up from small scale drawings too in a drawing office. Just the thickness of a 1mm pencil line at 1/24, becomes 24mm thick full size. So even if at 1/24 scale drawing was 100% accurate, you will still get an approximation at full size.
The only true way to do these things are to get the original co-ordinate plots (lofting lines) for an aircraft from the original manufacturer. John “Aeroclub” is spot-on here: The Hornet for example has had its length incorrectly stated in the 1946 and re-produced as fact ever since! This was not helped by the fact that AP’s gave packaging dimensions for major sub-assembly parts of the Hornet with an allowance for clearance too!
Even when you have some original drawings and some small pieces of distorted wreckage, creating full size drawings of something the size of a Stirling can mean errors of several inches could appear just by drawing a line to the information you have, which may or may not be ok?
