One Too Many
I talked it over with John (via email) and I'm getting the Perry A-2. Of all his A-2 jackets, the Perry has the widest back. That way, I don't have to size up to find something that fits me. I'm going with the seal brown, but the dull russet is an option. I just like the seal brown so much, even if more Perry's were russet color.
Good choice Joel. I sold a seal GW Perry 42-16175-P recently and the colour complements the brick red lining, knits and brass Conmar very well.
It's a comfortable jacket to wear too.
