Steve,
When I constructed my Roll Top Newspaper delivery van, based on just two original photographs, I was faced with exactly the problem you describe.
Although my scuttle is not the same as an AD it is very similar.
As I have only basic hand tools and no welder I adopted a pragmatic bodge approach, which may not be approved of by the purists - but it worked !
I made a join along each shoulder by using a joggler then overlapping the aluminium sheets which were were then fixed to the wooden frame with small countersunk brass screws.
After careful filling and rubbing done I was happy with the result and as the attached photograph taken a few months ago, shows even though the van was completed a few years ago the Join is still invisible.
