They were also sold in the US as a Peerless 35, a Hy-Score 809, and - briefly - as the Beeman 200. And in many places, especially the "British Commonwealth" as a Gecado or Geco. Some of the later ones, at least, must also have been sold as RWS, as well as Diana and Original.
No date stamping pre 1967 or late 1966 (some doubt which exactly).

For the knowledgebase, also sold as the Winchester 435
