But they wern't perfectly good engines, and I refer to the RCTS, Vol K for details, but the latter history is as follows. 3000-3019 had been previously purchased and were then new. Another 80 were acquired later and proved a very mixed bunch. Some were new, or nearly so, and some had been hard worked, and were effectively worn out. The GWR separated them into two batches. The best, numbered 3020-49 were united with their fellows and Swindonised. The remained, numbered 3050-3099, were beyond economic repair---they would have needed new boilers at least---and were run until they failed a boiler inspection: the last, 3093, going in December 1931.
