Looking for Old Puffer Jacket (Large) as a Pattern

[jwiltx]

I've searched all over this site looking at the MYOG stuff and I've seen some cool projects. Even Google hasn't helped me find a pattern that I can buy for making a puffer jacket. Does anyone on here have an old one that they'd be willing to part with for me to use as a template? I should be able to make it work with in any condition, but ideally looking for something with a hood in a size large.
