Well have four Wilaims PRR locos a PRR cabin car and a N&W caboose but no images. In fact the Williams brass K4 is what brought me back to O-scale in the 80's.
:Edit 10/9 forgot the two Weavers. A PRR Shrouded K4 #3768 and a Southern Shrouded PS-4 #1380 "Tennessean."
But the biggest brass engine was my last!
