Accuracy of Drawings.
Many years ago I spent many hours in my then favourite hobby of plastic modelling.
A very well respected member of that community did an article on the P-51D Mustang comparing different models and different drawings.
There were quite a few differences between them, now you would think that aircraft like the Corsairs and Mustangs would be very well documented,
but it appears that different people use different sources.
People who do colour side profiles often start with borrowed drawings so unless you know that they are meticulous with their own research for that
profile be careful about using it. Also I have seen different colour profiles of the same aircraft with different colours.
As a general rule I look for 3 different sources and compare them, if there is still no consensus of agreement between them I look at as many photos
of the period aircraft as possible to compare the drawings with. Photos in the old days were often airbrushed so that is always something to consider as well.
Finally, you have to be happy with what you are doing, as well as remembering the learning curve that you started with.
My first plastic model aircraft was a Grumman Avenger and from memory the wings were on back to front with more glue on the transparent canopy then there was plastic, but hey I was proud of my work back then.
Enjoy your previous work - if you want to do a rebuild/new one then get the resouces to a point that you happy with and build away.
