Euan,
Thanks for the information and the photo.
I will take a good look at the one I have my eye one, when I make the trip up to sellers / givers property. Hopefully that will be this Saturday afternoon. I do like the look of those roofs (rooves?).
An added advantage of the sunshine roof would be not having to do a major rebuild on the roof hatch. I have two that I could make one out of, I guess, but both have rested corners on hinge side. If all corners are the same, that would not be a problem.
This afternoon my Wife tells me the credit card is filling up again, so it stands to reason that my upholsterer would phone only minutes after, to tell me the canvas side curtains will be ready for me some time this week.

Thats OK by me though. I really want to get em home and see how they look in place. No point in being the richest one in the cemetary!!!!!
