Authentic hood mounting?

The tops on the new ND Miatas are like that BUT they have a plastic drain tray, drain tubes and drain filters.  

I thought that some kind of drainage would be advisable - but then I think ‘would they go to those lengths 60 years ago?’.

probably no.

which is probably why cars used to disintegrate in 10 years...

This looks it sits on top of the rear deck - not inside of it (like Miata).  There are no snaps for the top as you wanted.  I think this is the way Beck did Lane's red Beck.  I assume it has a hidden metal strip that is clamped to the rear deck. Snaps are there for the tonneau.

@WOLFGANG I like this look. I wonder if with snap expose can be converted to no snap expose. 

Looking at it all a bit further, then it seems it’s inside and on top. There’s a hoop running round inside the top of the tub, over which the canvas threads. This is then clamped in place with simple tabs. Then there’s a flap on the outside of the hood that covers the gap between tub and hood. And then yes, the studs are only used for the tonneau. It doesn’t seem difficult to do - bend a tube/hoop to fit the tub, fit and get an upholsterer to sew on the flap. The existing material can be folded in to enclose the new hoop.
The primary advantage would be that raising the hood could all be done from inside the car, with only the snaps behind the door needing to be fastened. 
I think I’ll have a go soon...

On my Beck there was a large flap of fabric on the top that was glued between the body and the carpet lining the area behind the seats.  The top was "permanently" bonded to the car (quotes indicating that it could be removed if necessary).  When I replaced my top I became convinced that the car could be picked up by the top fabric, it's that strong of a bond.

If I remember correctly, like Wolfgang assumed, there is a bow attached to the top bows, that hugs the rear deck with a bolted tab in the center.  The bow is sewn into the top material.  The rear of the top sits on the deck when the top is retracted.

On some Thunder Ranch cars, a dress molding (fiberglass) sits on top of the rear deck, held in place with bolts.  A piece of heavy but pliable plastic is sewn into the back edge of the top.  When the top is put up, the bolts holding the rear molding are loosened, the plastic is tucked under rear molding and the bolts tightened.  When the windshield clips are connected and top bows are up and locked, it tightens the top no snaps used.

Hope this helps.

Addendum: The set up I described was how the original Porsche Speedsters were done.

Thanks - I did more research and found just what you said. It’s really not hard to do - just the sewing part is beyond me right now. But I know I’m gonna do it before I’m finished..
