Wow...those photos became quite large! Anyway, "Humpty Dumpty" is a standard size 10" disc with matrix 81488A.
"Sweet Sue"'s matrix is B23751-1 and is the edited version - it is an 11" disc with etchings before the lead-in groove that show the pressing date of 11/23/38. What is wierd is that the this matrix is not the matrix for Columbia's 10" edited pressing for album C-29. That matrix is W24050. The matrix on this 11" disc looks to me like a Brunswick number. Was this then a custom pressing or was this to be issued as a Brunswick release?
