On Jubilee 5152 (The Four Tunes), the two sides appear to be recorded roughly consecutively (matrices: JB-1-308=3 & JB-1-309=2). With running times of 2:11 and 2:15, there is the same amount of run off at the end of each side.
However, on the later side there are three times the grooves used to cover the same distance. Why? Does this reflect a change of engineers or a change of equipment?
Could it possibly relate to the tempo of the tune? A longer run off would equal a longer pause after a slow song, for example.
I've included some images of a similar Guy Lombardo disc, but these two sides were recorded a couple of years apart, and on different sides of the continent.

On one side of my copy of Columbia A-3390 (Mary Stafford & her Jazz Band), there is a heavy scoring on the label, spiralling right to the spindle hole. Is this a runaway run off? Does anyone else have it on their copy? The scoring is raised, but it's hard to tell if it goes thru the label from the surface, or if it is under the label, as in a production error.
