I recently picked up this nice old Peugeot. I didn't realize 1x was a thing. The broken black plastic Simplex FD was supplied, loose, not on the bike. I dug thru my extra parts bin and found a Shimano Exage that works fine. It just looks wrong without a front derailleur. If God had wanted us to ride 1x, He wouldn't have given us a front derailleur.
