How about an A-2 ? Though, I am pretty sure the lining of an A-2 is more often than not nylon. But it fits the short and warm specification without looking like you're playing dress up.
The Buzz version is nice if you can find one.
N1's are tricky because IMO the ones that are actually nice and really well made are also the most repro-like and hence are a very slim fit. You might try the Mister Freedom N1H. Likely more inspired-by and less repro.
Not even sure it was this thread, and sorry for the dredge, but who makes your favourite N1 jacket in a non-slimmed style? I know @JB had some ideas. Doesn't have to be N1 specifically, but it needs to be short, warm, natural materials and made with more attention to quality than price point.
