These 10 ton 4000 gallon non-streamlined tenders were of welded construction and had a conventional layout with rear steps, tubular air vents and a single tank filler. Five were built and allocated to locos 6230-4 from 1938. However, from 1945, 6230/31 were paired with destreamlined tenders (Comet Models code TK9). One of the non-streamlined tenders was paired from 1946 with 46223, the other ran behind various engines, but chiefly 46247 from 1952-61.
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 destreamlined welded type, and the rivetted pattern allocated to the Princess Royals.
