Tony sez:

If the word "Simplex" is prominent on a truck, make sure it is not the
bolster that is so labeled. The side frame is a separate part produced by a
different company in general. Simplex bolsters were used in many different
side frames over the years.

Well son of a gun! That would appear to be the case on the T-section
trucks under the L&N flat I posted earlier!

Thanks!
