Peter Kerslake says "4505 lasted in service until October 1955 when it was withdrawn from St. Blazey. It was built at Wolverhampton Works in February 1907 as GWR number 2166. Together with two other classmates it was loaned from new to the Rhondda and Swansea Bay Railway in South Wales becoming their number 32, and two years later was moved to the Port Talbot Railway staying there until about 1912 after which it came back into Great Western service."
