Raleigh took over Phillips in around 1960, I believe, so after that point, the Phillips 3-speed was a somewhat lesser version of the Raleigh Sports. I have a 1959 Phillips Manhattan 3-speed (kind of the project from hell, actually), and the Phillips name is stamped on just about everything. However, it does have a Sturmey Archer rear hub, so that's where the dating info comes from.

Here's what Sheldon Brown says about Phillips from http://www.sheldonbrown.com/english-3.html#phillips:
"Phillips, a division of B.C.C., Phillips, based in Birmingham, was the second-largest British bike maker until merged with Raleigh as part of the TI takeover in 1960. Raleigh-made Phillips models are near the bottom of the quality range. Birmingham Phillipses often featured a chainwheel with the word "Phillips" prominently featured in the cutouts."
