Avorio Prassone AP info?

[clipper1801]

Yep, another obsession emerges from the clouds, I read the threads of the past, but does anyone have the specs on the Avorio Prassone AP balloon card we have in our sets?-mostly a length and any rigging info would be great.



Clipper dealing with inflation . . . or is that infatuation?

I've this nice italian book:

Giuseppe Magrin - I palloni della Guerra Storia ed evoluzione dei mezzi di volo dalla Grande Guerra al 1930 - Gaspari

where I seem to remember there are info about Avorio-Prassione AP. I'll look this evening if there's a specs table (there are some technical drawings, I hope to find that table).

Hi Clipper!
I know this is not a Prassoni but maybe this rigging chart might help you.

Clipper, did you ever get around to building this one? And if so, what does it look like next to the other drachens?

In case anyone else is thinking of building their own...

Here are the documents I used when modeling an Avorio-Prassone balloon for Shapeways. A nice set of guides if I do say so myself, and now safely out of copyright. It looks like there were at least five sizes available. If I remember, it was considered more advanced than the Parseval-Siegfeld (Sausage) or Caquot balloons, which is why the basic shape lived on into WWII.
