That concludes the history of the original 35 new boilers built for the Class A4 Engines. One of the, (what I think),most amazing statistics to show up from the above, is the history of the Boiler No. 8905, first fitted to Eng No. 2509 SILVER LINK in 1935, and finishing its career 29yrs and 1mth, and 10 Uses later on Class A3 Eng No. 60062 MINORU. In contrast the 4th boiler 8908 fitted to Eng No. 2512 SILVER FOX only had a career of 14yrs 10mths and 4 Uses, and spent 3years 10mths out of use.

Not all the Boilers were as well used as 8905, as 8mths after Boiler No. 9031 was fitted to the last A4 to be built, the first of 5 spare Boilers was utilised on Eng No. 4487.
