Italian studio pottery big orange jug

I bought this big orange moulded jug from a boot fair recently. Impressed mark Handpainted Made in Italy and number. Looks 60s/70s. Who made this type of thing? I have picked up a few pieces of zany post-war Italian handpainted pottery in the last few years. Can anyone tell me which Italian factories made that kind of thing? Thanks for any help.

Thats strange i was at my local boot sale last week saw the identicle one plus another one for lemon should have bought the pair for £8 silly me .

There's a similar one made in Bassano, Italy. There's also a lemon shaped on on google. Seems they are a speciality of the region.
