1937 Cabriolet gutter and rear interior?

[Roffeman]

I mentioned this in my post about the car that but it's worth mentioning again:

I am glad to see all the positive and helpful feedback even though I am pretty much a newbie here...so thanks.

So I am looking at my '37 Cabriolet and there is nothing under the top when it is folded down. Should there not be some sort of channel or something?

Also, there are no side panels on the inside of the quarter panels. There are upholstered panels on each side of the rumble seat...or mother-in-law-seat as they call it in Sweden

Right now I can look back and see the rumble seat. Is there some sort of bulk head that should be between the seat and the back area?

Any pictures or diagrams links would be great.
