I've been meaning to post every time someone writes something like that, so don't take it personally (and don't let it detract from your solid haul): Guys, working cuffs aren't all that uncommon on casual coats. I've found them on a bunch of cheap stuff - even a (pre-SF) BR coat of mine has them.
Thanks, that's interesting. I've never seen them on casual jackets or coats before and was surprised to see them this time. But now that you mention it, maybe I've never seen them because I never looked that closely.
