Seems odd to me that there would be that little to no stretch after all this time....

It isn't necessarily that the chain has little stretch even after 12 years. Chains don't stretch over time, they stretch over miles. There are lots of bikes that age with less than 3k miles on them, so the condition shouldn't surprise you. OTOH, just in case, did you put a bit of tension on the chain to ensure that all the slack was taken up before measuring?
