I think you are right. The Exploit shifters do not look like Syncro 1 or 2 but the levers look close to Syncro 2. The mechanicals look different. So I suspect the levers are from around 1989. Hence, why it would be great to understand more about the Exploit series. The workmanship is excellent as is the finish.
