JC, apparently I am not familiar enuf with the proof process alhto I have seen the old lithos in Greener of the single tubes flying off the tables into the sand. Spoke too soon and I certainly don't doubt the validity of your source or your interpretation. The tubes of my poor little 3-frond Charlin must have been stuffed from front to back. Need to do a volumetric calculation to find out just how many inches of 12 bore that "superieure" mess would occupy.
