u-u-u-uh-h-hm. I have two PRR centipedes. Mine are not BLI, but brass, made by OMI. I just got them from a friend's estate. They are brutes. His minimum radius was 23" and the engines didn't look bad tracking around those corners. At least not as bad as a Big Boy swinging around the same corner.
I doubt that the BLI engines can match the standard of the OMI models, but to have one, or two, would be neat. I doubt that I purchase any, but those that can't find, or afford, the OMI engines, might be tempted. And it may be worth the sacrifice.
I like the "oddballs" like the centipede, the BL2, DL109 and such. Call me "feeling sorry for the ugly duckling" if you wish, but beauty is in the eye of the beholder.
I think quite a few will be sold. Anyone modeling that era, especially the PRR, should have one.
