The streamlined tender was fitted originally to locomotives 6220-9 and 6235-52. The full height side sheets at the rear meant that two hatches had to be provided for water filling, and hence two water fillers, which remained when the tenders were cut down to the standard rear profile when streamlining was abandoned from 1945 onwards. In the destreamlined condition this was the commonest pattern of tender within the class for the longest period of their existence. The rear ladder meant that no rear lower steps were fitted on the underframe.
The tender underframe had standard axleboxes. Water sieve boxes were an Ivatt introduction fitted to newly built tenders from 1946. Photographs suggest that they were also quickly added to all earlier 10 ton tenders, including those of the non-streamlined welded type, and the rivetted pattern allocated to the Princess Royals.
