The #43 R.A.C. set was introduced in Meccano Magazine in October, 1935.  Like the Police Set, it consists of a hut, a motorcycle, and two uniformed men or guides.  The main difference is, the hut is not diecase like the Police set, but of tinplate, and somewhat smaller, probably explaining why it was the least expensive of the three.  I happen to like the colors of uniforms that the guides are wearing.....light blue, with hand painted accents.  Anolther interesting fact is that all three boxes are slightly different in size, with this one the smallest.
