Best of luck with this Ron.
I suspect however that you may well continue to have problems with the question of Originality.
AS a long term MK 1V owner myself I know exactly what you are going through.
MY personal perspective is that although we would like to argue it is an original car. The facts are against us. The cars were built by Brian Angliss' company in the 80's and 90's, and not the original AC cars ltd. Although it can be claime same bucks, factory personal etc , most people will put the cars in the same category as the continuation cars, and copies which are still being built today, some, by companies titled AC cars.
I have learnt to relax with this because the car is as close as I can get to a 60's car, with the best familly line that I can manage.
With prices of some replica's now exceeding some MK1V's I suspect you will have an uphill struggle for a while yet!
