I have tried several times to replicate a model I built long long ago that met it's demise, was stolen or given away.
Only one came out close.
The main problem is if you didn't build it straight out of the box it is almost impossible to find the same parts you used to make it your own so when you are done it just does not have that same feel to it.
For sure you cannot replicate the pride you had in that original build, just cannot capture that excitement that came with the planning and execution of the project.
That is why while I will build some of the same kits that were lost years ago because I really liked them, I don't try to replicate the past.
