Turns out I was fooled by the "BLT" date on the Athearn. It shows 1925 but the X29B was a rebuilt done later on, and I guess that's why it has a 1950s paint scheme (or it's just a poor stand-in version). It's not a huge deal for me, but as famous as the PRR X29s were, I'm surprised their isn't a better or bigger selection out there.
I just want to find a fairly accurate 1930s version to roll behind a PRR M1a. If anyone knows I'll be grateful for the info.
The best choice for the X-29 boxcar for the Pennsylvania Railroad is those produced by Red Caboose. A while back, Red Caboose transitioned their production to Intermountain Railroad Company

This is what might be referred to as a 1934 build with dreadnaught ends, Superior doors, type AB brakes with brake gear on the upper corner of the end. The paint scheme is one of the Circle Keystone schemes
These are generally the cars that others try to compare to.
Since the transition, releases of the original X-29 (or X29 in Pennsy lingo, no dash) have been delayed.
The current release is now scheduled for December 2012, original release was supposed to be August 2012.

There are two versions, the original builds, 1928, with "K" type brakes and brakestaff with brakewheel above the roof. The ends are flat plate. The next build, 1934, have "AB" brakes, brake gear and wheel on the end of the car and dreadnaught (rippled) ends. There were many paint schemes as the years went by.
Good information about the X29 and all things PRR can be found at Jerry Britton's Keystone Crossings website.

The Athearn and MTH cars do not resemble the original X29, they may, in some small way, resemble the rebuilds of the X29 to X29B cars. These were original X29 cars that had their bodies replaced with newer bodies on the old underframe.
The Red Caboose versions sometimes appear on our favorite online auction site . . . as well as the Sunshine resin kits for the X29B.
Many years ago, Train Miniature produced the X29, a reasonablly acceptable replica of the prototype for that era of model railroading. Walthers still produces the same car under their name.

This is the 1928 build version (they started building them in 1928 and continued for additional years)
This one has the flat plate ends and the "K" style brake system with the brakestaff and brake wheel above the roof as well as Creco doors. This is one of the Shadow Keystone schemes.
