If anybody's interested, there's a loud PRL x Corneliani made in Slovakia. It's partially lined and single vented. It a pretty true to a 42L but I don't have any measurements. I would say about a 44 to 45" chest, 26 to 27" sleeves and probably 19.5 to 20.5" shoulders.
It's 50% off tomorrow (about $17.50 plus tax). Available for proxy at cost plus shipping if you're interested.
