During visits to Great Britain in 1977 and 1980, I visited a number of steam railways, and I saw quite a few of the Barry engines. Many of them had only recently been liberated from Woodhams, and I had my doubts that most would ever steam again. I am thrilled to have been proven wrong!
One advantage that our British friends had was that they could acquire multiple engines of the same class, sacrificing one to provide parts for the others. I know of several groups which purchased three or more engines knowing that one would be the organ donor for the others.
Dai Woodhams, the owner of the scrap yard, had a heart for steam locomotives, and when he decided to sell locomotives for preservation, he sold them for what he paid for them. He wasn't out to make a killing.
