Martini says he doesn't make quarter ribs. I assume he means he doesn't make them except for his own work. It seems to me that the major barrel-makers might want to have ribs made for their contours and have them on hand. The demand may be small, but some good CNC shop should be able to grind them out at a fairly low cost. Another product I wish someone would take up is Biesen butt plates. There is no comparable one available to my knowledge, and I just used my last one.
