https://i.imgur.com/nX1R4tY.jpg saw this on rustyzipper today under men's wool coats second page. I have four of them, it was so hard not to buy it. Should still be there.
I have one of those, things have changed in the last few years, one could by vintage wool shirts and jackets all day for $15 to $20 on eBay several years ago, now the same stuff is $50 to$100.
I have a Woolrich brown check shirt very much like that but a little newer. I used to wear their grey heavy wool shirts but the brown check has been my to-go-to shirt for 2 years and it works great with my ASAT. If I didn't have so many wool shirts I would definitely snatch it up
