Hello Richard.
This action is the " Wood Brooks 90 Degree Action. "
In 1947 this was sold as a '' Grand " action in a vertical.
This was how it was presented in the shop I worked
in at the time.
We found that it would work fairly well if it was regulated
and well lubricated..
There is a model of this action in the PTGF. Museum.
It was mostly used in the Everett and Story Clark pianos.
Hope this helps.
Regards
Jack Wyatt
