I found the same.
In 30 plus years... i have never seen or heard of this..
Well anyway i guess i have a one of a kind tank!

On my 71(Oct of 70 SPD), I only have 4 on the tank and a separator tank in the left wheel well. No other tank mounted anywhere. I don't recall seeing a tank with 5. Could it be something because of being a CA car? But yet, I've seen CA cars and the owners didn't say anything about a 5 nipple tank too.
