Re: GATX 7167 - The Pierce Company

   Nice photo of The Pierce Company tank car, Bob, the identity issue not withstanding. 
I wonder if I have missed something when looking at such photos in the past, however.
What are the two round pieces protruding from the frame and showing just above the outer
wheelset in each truck. I've never noticed these before and wonder if they are related to the
draft gear or what purpose they served.

Cordially, Don Valentine
