Just a note to clarify. The Big Hauler valve gear was never referred to as Walschearts, just “fancy” valve gear, and it was always all plastic. The simpler form was referred to as Stephenson valve gear. The Annie has metal Walschearts valve gear on some models and metal stephenson on others.
The new set versions with the Annie seem to be comparable to the single packaged Annies. If not I would like to know and will stand corrected.
