Hello James: I know some, and I have the Pat. numbers. I will have the Pat. info. in a week or two. I understand there were 6 of these actions installed in player grands. The last tract of one was in N.Y.City a few years ago. It was a simple action compared to the one we use now. I have a diagram in my files that is somewhere. I just moved and there are a lot of boxes. Jack Wyatt;
