I would urge anyone interested in GWR to get the J.H. Russell series Pictorial Record of Great Western Engines, as mentioned by richbrummitt. They are a fascinating read in their own right, a great aid to the modeller, and will probably inspire you on to further conversions. Yes, they are expensive, but that reflects how good they are, and you will not regret buying them. The 517 is in volume 1, (Gooch Armstrong and Dean).
