I got curious (I'm stuck home with a code in the doze, fortunately not communicable via the internet laugh ) and looked up the current Montbell down hugger #1.

The EN comfort rating (the one you want to focus on) of the new bag I looked up is 24*F, which is probably fairly similar to the bag you are looking at unless it has lost down over its years. It of course may not be exactly the same model as the one I looked up. If the bag is in good condition (which, frankly, I'd question given the price), I'd rate it in the mid to upper 20's F.
