I'm hoping someone can help me identify these Campagnolo monoplanar brakes, and suggest new pads for them:

Front:




Rear:


From what I've read, I can use Koolstop pads, but I'm not sure which ones. I also get the impression that the Campy pads currently on the bike are not correct for the brakes, and I should instead have a brake shoe similar to what's shown here:


Any suggestions on what I can use as replacement pads? And, should I start looking for brake shoes on eBay?

Thanks!
