It is an 82 model, not 83 as I originally stated.
Just on the gelcoat / paint, we've already gone done the repaint path, and refurb the clear over the flake as it had broken down badly in patches. There were a number of deep scratches and some damage in the gelcoat as well. We had an experienced boat painter in Melbourne work on the hull. It was a bigger deal than any of us expected, but hopefully the results will be worth it. We'll be able to upload some shots hopefully this week. Here are some closer pics of how it arrived.
