Thanks to an Archival follower who conjectured that that Rivendell’s Wooly Warm sweaters might be coming from the same knitting mill as vintage, UK-made LL Bean sweaters from the mid-1980s. Both come in a a similar shade of sea foam green and resemble each other in terms of overall styling (heavy of the rib knit).

My fave are the ones the come in a pixelated camouflage plaid:
