This looks basically identical to a Salomon STH Driver binding, a progenitor of the current STH2, one of the best on the market.I’m very curious now as well so I’m attaching some photos. I was also able to find my email receipt from backcountry back in April 2007 and the line item description calls it FFG 14 Driver binding.
But your problem is actually different: unless your new boot has radically shorter/longer sole than the old boot, redrilling will place the new holes too close to the old ones. In this case a new binding with a different hole pattern is a safer bet. This STH is a great binding though, I'd keep it.
