I have an old 30's vintage Delta bandsaw and I am missing the sliding blade guard for it. I am meaning to replace it and my question is this: Is the sliding blade guard (near and above your hands when working) the same (size) on the 10", or 12" or specifically the 14" bandsaw? There seems to be a glut of info on the 14" and the guards are more readily available, but I can't seem to hunt down the answer to the commonality of parts on this. Does anyone know?? Thanks.
