The bag itself is pretty heavy, if you dont mind its pretty cute. Did you check ebay yet? I think a lot of people are willing to ship international.
I'm sure someone can help you authenticate here If you find one just make sure the seller is reputable.
Reputable? Im sorry, im not sure i know what you mean.. And it would be the first time that i buy something at ebay.

Im not sure if all of them are the large version? But these are the ones that i looked at.
i had a luella giselle bag. i've sold mine though as i rarely used it. while i like the style, i find the bag heavy and a hassle to get in and out things (esp. with young kids). i paid £515 for mine a few years ago.
