CB&Q 9281-9292 were so-called Phase IV SW1200s, among the last ones built, and as such have a few differences from the LL P2K model.
The Life Like model has rounded buffers above the couplers; this is correct for an SW9, but not an SW1200. It also has a six-louver battery box and three lifting eyes on the side of the hood, correct for SW9s and Phase I & II SW1200s. Finally, the Life Like model has solid handrail stanchions, rather than the channel-style (like on Geeps) found on Phase IV SW1200s. It does have the large stepwell openings, which are correct for Phase II, III and IV SW1200s.
There is a good discussion of detail differences between the production phases of EMD switchers in X2200S #41.
All this said, I run a stock LL P2K SW9/SW1200 in CB&Q livery on my layout and sleep just fine at night. :-)
