The CD 162's were found on the Pennsylvania Railroad. The blue aqua unit second from the left has nearly mint micro drips. The CD 133's were found in very limited quantities along the B&O. One is from the main line at Tunnelton, West Virginia and the other from the Keystone Subdivision near West Newton. I might have found a total of three or four of these in all the years I've been collecting. My friend Lee Brewer has a sooty unit that I pulled down in McKeesport Pa. The boring CD 102 was found along an overland phone lead off the National Road near Washington Pa.
