I bought this navy flannel Brooks blazer years ago from Patrick on the exchange here, and basically never wore it myself because I didn't bother to get the sleeves tailored to my length and ended up deciding I had other blazers that already fit better. Was initially attracted to it because I didn't have any jackets with a chest patch pocket.
Labeled 42ML -- I believe that means "medium long". Fits like a 42 reg.
Patch and flap hip pockets, and patch chest pocket. Definitely heavy enough material to warrant wearing in the cooler months.
I haven't had a chance to take pictures but will do so next week, but am posting to meet my wife's threshold of "post these things for sale or giveaway before I take them to Goodwill!" in her current summer purge.

I will post the measurements now, and like I said will post pics when I have a chance.

32.5" length from top of collar
22 pit to pit
18.75 shoulder to shoulder
23.75 sleeves with at least an inch to let out
