Avery, Who knows what evil lurks in the minds of Balswin? They were nexer so bad as to come near to Chickering in terms of changing designs. You may have a transitional design that is neither this or that but something else. If you can get Baldwin to search their files you may get an answer. In the meantime I think you are on the right track. Check one or two out and see if you get better results with elevating flanges in terms of regulating results. Lots of luck and thanks for the answer. Newton nhunt@gandalf.rutgers.edu
