20137 basks in the morning sunshine in Toddington Yard, on the Gloucestershire Warwickshire Railway, on 10 August 1995. This is the kind of picture that fully exploited the quality possible with the Pentax 6x7. A static subject in full sun, tripod mounted camera, 1/60sec f16. Higher quality than most present day digital cameras, but a scanned file size of 200MB!
