Hello Richard, You have a Wood-Brooks 90% action. This action was actually invented by the Thayer Action Co. just before they merged with Wood.-Brooks. In the late 1940s it was introduced as a "GRAND ACTION" in a vertical. I was young and believed the " Factory Experts " Checking was a problem in some cases we put leather on the hammer tails, this worked very well. To help this action it needs to be well lubricated and add a little key depth. You will find a working model in the Foundation Museum.
