Can anyone recognise this hull design?

Hello,
I got my hands on this mold. I think it is Italian, but not 100% sure. Can someone recognise it. What manufacturer is it from?
It is 6 meters long.
It has spray rails only on the bow area and flat surface at the most aft of the keel(What is the word for that in english.....?planing plate? sorry for my poor vocabulary)
Best Regards!
Here are some pictures of the hull

 

Ok, if we can't recognise the make and model of it, then can you predict its behavior comparing it with this boat(as i know perfectly how it behaves):





Weight is about the same on both - 980kg
Length of the first unknown boat is 6 meters, on the second is 6,2 meters
Beam of the first is 2.5 meters, on the second is 2.25 meters

The first has one short spray rail only on the bow area, the second has 2 spray rails along the entire hull length
The first has this flat surface at the most aft of the keel(I don't know the word for it in English, on my language we call it planing plate) and the chines are longer aft from the transom and also at the the very end they become more narrow comparing with the first one that has all the same profile of the hull on the entire wetted length.
See the following picture


Tell me what you think of this. I'm designing a deck but i can't decide which hull to use for my project.
Target speed is 50 knots and i know the second hull is more than capable of this speed but the unknown hull is a bit shorter and wider is this better?
