Got one setup on my Ranger 3-speed, an old Schwinn Approved setup with the round, metal, bullet shaped headlight. Have another on the shelf which is going to go on Maggie's (either) Schwinn Breeze (currently on the road), or Raleigh Sports (on the rack getting refurbished) once she decides which one she wants to ride regularly.
And I grab any and all generator setups and parts that I can get. Yeah, they drag on the wheel. They're nice to have on our Saturday night rides in tandem with a battery or rechargeable light set, that way if we're running out past the battery life we've always got the backup. And even in bike-friendly Ashland, VA I don't complain about having a double lighting setup.
And as for period correctness, I love them. One of these days, though, I've got to start messing with a Dynohub.
