Bersaglio mystery

Bersaglio Spoke II Super crystal chrome. Do they actually exist? Does anybody know where on earth you can actually buy a set of these stunning wheels? Apparently they are the same as Lowenhart BR5 but without the crystal chrome effect. www.hartwheels.co.jp this is where I found the most detail about them. No reply to my e-mail enquiring into it. Its like they dont want to sell any. A company in the UK gave me a price of £3925 sterling, about €5500 and $6875. Seems a bit steep for 18"s. Cheers for any help!
