Not much luck here with originals, I'm a 46 chest but a 48 Shoulders. Anything under 21" across the shoulders just doesn't work. I've purchased of recent times an XL 70's Alpha and a 90's 'Ground Pounder', neither fitted in the shoulders & importing them was an expensive exercise. Over here in the UK issue MA-1's are rarely available. On the N-2B & N2-A front I've had more luck due to shoulder width and own three originals in XL that fit a treat.
