Michael,
We know that Kleinow (Boston) and Smith (Both) were printed near the end of the 350/460 RP print run (for more information on this see my post on the recent thread on Demmitt and O'Hara started by Ted Z.). And it seems from this survey, at least preliminarily, that these two subjects are overrepresented with Polar Bear and Piedmont Factory 42 backs. This suggests a possible sequential printing of the 350/460 RP series in which at least the lion's share of the Polar Bear and Piedmont Factory 42 backed cards were printed near the end. Note that this is consistent with Factory 42 being a later factory; there are no Factory 42 backs the 150-only, 150/350 or 350-only series.
Any connection between the overrepresentation of these subjects with Polar Bear and Demmitt and O'Hara (St. Louis) is not clear to me; although it is very interesting that all four of these "team change" subjects were printed disproportionately (in the case of Kleinow and Smith) or solely (in the case of Demmitt and O'Hara) with that back.
