Well I could do it, as reconstructing records from chaos has always been part of my job. The problem is, assuming permission was granted for such an endeavour, how many build book summaries could be posted onto a spreadsheet in an hour?
You would need essentially the build certificate details.
Chassis number
Body number
Build number
Model
Paint colour
Interior colour
Hood spec
Wheels
Other extras........................
Date of start and finish of build
One every ten minutes would be six an hour, so fifty on one long day. Assuming 800 cars a year, 16 days of graft for one years production. But towards the end you get the gaps, and they take much longer to resolve.
So ten years of production would be at least 160 working days, at five days a week, meaning 32 weeks. Realistically, ten years production could take a full year.
Think of the accommodation and subsistence costs......................
The best moment to create a production record is when the cars are signed off.................................
