As some one else pointed out 30853 Sir Richard Grenville lasted until December 1957 in original condition before having new cylinders and smoke box fitted, 30851 Sir Francis Drake lasted until withdrawal in December 1961 with the piano front and short smoke box although it had the later smoke deflectors with out the steam pipe bulge over the cylinders, this was due to a mix up when it had new cylinders fitted in 1949 with 8” piston valves instead of 10” so depending your modelling time scale two more locos in BR livery from renumbering 30863. One thing that Hornby have got wrong on 30863 is the yellow triangle under the number, this should be a letter A the same colour as the numbers, it looks like they have used a photo of the loco in the Irwell book taken ex works at Eastleigh in 1949. The letters on LSWR and Southern Railway locos built and overhauled at Eastleigh referred to the locos power classification, Ryde works on the IOW also used it and it was usually displayed on the running plate behind the front buffer, in BR days it was applied under the number and lasted into the early 50’s when it was superseded by the BR standard code above the number, Ashford and Brighton didn’t seem to use this system. The yellow triangle under the number denoted that the loco had water treatment fitted, this was used in the early sixty’s when it replaced a yellow dot under the number that had been introduced in the mid 50’s, it changed to the triangle so the yellow dot would not get confused with the Western Regions coulerd dots that where displayed on there loco cabs for route and power classification.
