Specific BIFL waxed canvas jacket

As the title states, I'm looking for a very specific set of requirements for a solid built waxed canvas jacket. The specific style of the jacket is about the only thing I'm flexible on.

•Needs to have a wool lining, sleeves included. Wool blend is acceptable.

•Needs to have AT LEAST 12oz or heavier outer shell. The heavier the better, but no less than 12oz

•Needs to have gusseted shoulders so there is plenty of free movement while wearing the jacket.

•Needs to have a zipper front and wind flap/cover with button closure.

•And lastly, I'm a pretty big guy. It'll need to be available in not twink sizes. I'm 6'3"(191cm) tall and 240 lb (110kg) with an athletic build. I'm OK with ordering and lead times, as long as it's a few months or less and not into the years area.

Freenote cloth makes exactly what I want for 550$, but they're out of stock on the entire line.

Anyone have any suggestions on where to look for this very specific set of requirements?
