I am in possession of a largely complete list of locomotives produced by H. K. Porter and predecessors from 1867 to 1950. I am attempting to identify each narrow gauge engine with a specific railroad or company; however, up to 40% of the initial owners listed are names which I cannot associate with a specific railroad or company. Is anyone aware of a list similar to
www.shaylocomotives.com for Porter locomotives which identifies sunsequent owners or operators?
