Outlines of Power - Nº 3 : English Electric Class 50

Here we have the third of the 'Outlines of Power' articles by Mike Turner that the magazine 'Rail Enthusiast' ran during the early 1980s. 

This one featured the English Electric Class 50s with a fantastic portrait of 50003 'Temeraire' in large logo livery.
The accompanying annotation, which may be too small to see on the picture, reads as follows:

Mike Turner's painting of 50003 'Temeraire, in the bright new livery applied during the type's refurbishment at Doncaster Works, compliments Russell Carter's outline drawing of sister loco 50023 'Howe'. The Class 50s, originally leased to British Railways, were built by English Electric at Vulcan Foundry, Newton-le-Willows, in 1967 and 1968. A total of 50 are in service on the Western Region, although their early days were spent on the London Midland before the full electrification of the West Coast Main Line to Glasgow.
