Well, thanks to a free movie month on one Dish network channel, I watched some classics I had never seen before. One was Lawrence of Arabia which was produced in 1962. In one of the many railroad scenes in the movie I saw this one which contained two "Dry Spot" type composition insulators. These were used on British, New Zealand, and perhaps Australian lines and some specimens are marked with date codes (?) in the sixties which make them historically accurate for the period the movie was made although probably not for the World War I period it was intended to portray. Anywell, these are not pieces typically seen in movies and TV.
