I'll bet you can find one here that will: http://www.ronco-plastics.com
They make top quality tanks for a very reasonable price and have more
than 400 shapes sizes to choose from, including over 100 non-rectangular.

I aven't checked with plans, but I must admit: they have it for shure...
But... ONE tank ordered from california to Italy?

Ooops...

It looks a bit complex and
expensive...

Maybe not, if you know anyone who travels to the US (today people hop
all over the world as easily as going to the next town). When I still
owned my company, we sold tanks to people as far away as New ZeaLand and
Brazil...shipped from the mfr to a US a address to be taken home as a
checked luggage on their flight.

But if that won't work for you, there's a company in the UK--Tek-Tank
http://www.tek-tanks.com/Pages/frameset.htm --that also makes excellent
tanks and has a good number of different shapes/sizes.

If THAT won't work for you, I'm active on several websites that are also
populated by European boat owners...I'll try to find some European tank
mfrs for you.
