I bought these about 3 years ago on ebay and didn't really inspect them until some time had gone by; I then noticed that there was a crack on the left bolt hole (the pink triangle points out where). Anybody can have these, you just have to pay for shipping. I figured that somebody out there probably has a similar crack on a set of their own Onza brakes and could use the good side as a replacement. I live in the states, so if you live in the UK or Australia or somewhere else you'll have to send the shipping fee through Paypal because I don't know how else to convert the currency.
