Does anyone remember plastic model American styke locos and box cars being given away with cigarettes?

At least I think that they came with cigarettes as I was given them back in the late 1950s by the lady next door who smoked like a chimney.
They were an orange-yellow and they came as a loco, a tender, a box car and possibly a caboose, all American but these were in Shropshire, England. They may have come via a USA friend of the lady though.

Not found any reference to them via Google so I thought I'd ask here.
