In looking at some of the photos, it appears that this aircraft (in continental's configuration) does not seem to have wx radar, and also doesn't seem to have the radar that shows other aircraft in the vicinity. I do know that the 737-300 series aircraft built after 1990 have both, but these don't seem to.

I think the question is why do these B733 have mechanical ADI and HSI? You can see the weather radar on the pedestal. Most B733 have EADI and EHSI same as B734, but these must be early B733 without it. Are there many B733 built like this? or was this special for CO?
Not a CO pilot but that is a likely explanation. The US FAA is not likely to approve pilots jumping back and forth between semi-glass and iron gauges. They might well allow them to fly both -200 (with JT-8D) and -300 (with CFM-56) but not the different style flight instrument. Something similar seems to be going on at Southwest where they use their full glass cockpit to simulate pictures of round gauges.
USAir ordered their -300s with the same instrumentation as their older -200 fleet, presumably for this reason.
Happiness is not seeing another trite Ste. Maarten photo all week long.

BA for many years had dual qualified pilots on B732 and B734. The B734 have EADI and EHSI, but round engine gauges. BA and KLM both bought round gauges after the BM B734 crash at Castle Donnington which was attributed to misreading of the TV gauges.

WN 733's and 755's are the same way. They have the traditional steam gauges. I have been told that this was to ease transition between the 732 and the 733. Example, I am currently working on N642WN, one of the last 733's delivered new to WN, in 1997, and it has the mechanical gauges.

CO's -300s (737-3TO) TCAS systems were installed after the A/C were delivered. The radar indicatior is used to show other A/C positions and the VSIs have red indicators for fly up or down incase a resolution advisory is required when another A/C comes within so many feet of you.
