Here's another possibility for you: The molds in China are owned by China, NOT THE MANUFACTURER (it doesn't matter who or where they were made. IHC from Philly was put out of business by this, and today I was informed that S helper and Aristo craft were both victims as well.
It is possible that since Lionel had a working relationship with MTH (from what i've heard Lionel and MTH were made at the same factory), that some S Helper may be released as Flyer for the 75th anniversary.
Food for thought?
