maxifig parts missing

[N. W. Perry]

Before I go further, can you have a look? A lot of guesstimations here...

I'm probably guesstimating just as much, but I think the brim in back extends just a bit farther (maybe twice the width of the crest) and maybe curves more steeply downward. The brim might be a little thinner overall, too (but that can be deceptive).

Here's an image with a good top perspective. And here's a video where you can get a pretty good look at the inside/underside, if that helps.

But definitely looking good so far!
