I have a "Taco" l2 (ironically thats what we've always called it) and a '82 l2. Some of the welds on the Taco needed to be repaired and the main cylinder pulley was on backwards, but other than that, its been really good, ive even put a header reverser on it. But I've never heard of a Taco l3, the serial numbers on the l2's were 1-300.
