I have a piece 2" X 1/2" from the blown area. It came from the area adjacent to the straight tear near the breech. Measurement wall thickness is .112" at that point. If anyone would like the series of closeups etc of the Baker and could post them here please send me your email and I'll send the photos. Unless a loose primer was in the 8lb Clays jug, the loose primer seems unlikely. The only unusual thing is the rear of the tear seems to be following a weld line, if that is possible. Other than that, I don't have a clue. The photos give a good view of the evidence. Hope some new light can be placed on this incident. Randy
