1. Not entirely sure, but I would guess "yes"; similar era. I found a Marnold catalog (on line) which is dated 1960. I do know Walthers featured that line in their catalogs into the 1970s. The "Dual" MRC I posted is pre zip code, so it was made prior to 1963.
2. These are capable of powering my All Nation Ten Wheeler(s), so I would again guess "yes". As I mentioned, they also can handle the older universal type motors in the American Flyer S scale and the few Lionel Standard Gauge pieces I have.
3. Thanks. For whatever reason I really like the look of these older units... 🙂
