GE made wringers for a good number of years, possibly as far back as the 20s and 30s, I believe. In the post-war marketing rush and into the 50s, GE offered wringer machines for sure. The washer in the photo would probably be a 50s model, but I don't know enough about the GE wringers of that era to be sure.
Our family had what was claimed to be a 1952 GE wringer for a few years in the 1970s - it was intended to be used at the country home we were building in the Laurentians but which we never completed. I remember that the wringer came in darn handy when the ol' V12 washer went bad on us in summer of 1973.
Even more interesting, there is a GE version of a washer with a spin-drying compartment (like the Easy models) - I am not sure when those were made, though.
