No, definitely Sikorsky H5 or Westland Dragonfly, the same looking wise, but Airfix catalogues started in 1962 and first ever plastic model was mid 50’s. Their range did not expand till the 60’s and cannot find this item from that time, as this chopper dates from 1949 to 1951. I would be staggered they would use something as fragile as an Airfix type model, but then again would explain why some were replaced. As I say I would expect some weight in them as well to help the drop after win. These have springs to act as dampers for the drop. They would have to have been movies if models anyway to support the rotating rotor which needs to be free running. Mine are all metal..
