Hello Ron, The W._ at B_ (mailto:W. at B) . 90% action was presented as a "Grand" action in a small vertical in the late 1940s. I think the ones we had then was the Shoninger brand. We found that the action regulation was not reliable. The best remedy we found was to reduce the hammer blow a little and or increase the key dip a little. In extreme cases when checking was the problem we would use back check leather on the hammer tails. Most of the 90% actions will be found _Story at Clarks_ (mailto:Story at Clarks) and Everetts. Richard Bittner has more experience with these actions than anyone I know.
