Looks like the same model as mine, apart from the Alpine roof windows.
If you happen to track down the name or code of the red paint please would you let me know? I have not been able to find any to match mine.
Mine came from a farm and had been used "properly" - it had / has the same areas of corrosion, but worse, I have made a start, see pics, I must say yours looks great.
I chose to fill and treat the rust on the rail around the middle and then spray gloss black, but I think I will return it to the original red once I can get hold of some paint.
Hang on to it! Its a real nice one.
If you sold that you should be getting at least £4K imho.
