Milo Baughman Couch? One on ebay says it is attributed to MB - but...also 1st Dibs has a love seat ---??'s  

So I bought this couch pictured below for $20 (I personally collect and resell, no store) - I love it and thought it might be a MB and found the identical couch on ebay and then 1st Dibs - however ebay says its "attributed to" MB - I know what that means...nothing...and 1st Dibs says their love seat https://www.1stdibs.com/furniture/seating/loveseats/petite-milo-baughman-chrome-flat-bar-sofa-loveseat-mid-century-modern/id-f_1338934/ came with two MB chairs in the same fabric so they identified it as MB -- is there a book, catalog or other way to identify this couch for sure?
Quality construction with curved wood under supports which leads me to MB...but if anyone is an MB expert I would love your 2 cents
