During this period the following Orders were placed by Ivatt (1851-1923). The Locomotive Drawing Office no longer recorded the Progress Number within a BO, now that boilers were being given registered numbers in the Boiler Shop.

BO537 (14/3/1901). 6 domed boilers intended for 8ft-singles, making use of spare material. These boilers had 3-ring barrels, and domes. Note added “Made for 7′ 6″ engines to N119 drawing.” There was little demand as evident by the time taken to complete this order, but the 3rd boiler came in useful when it became necessary at short notice to find a smaller boiler for Ivatt’s prototype Class L1 0-8-2T No. 116.

Boiler Nos. 1422-30.
SO532 (undated). A Stores Order for 9 miscellaneous boilers
Being for an odd number of boilers, it seems likely these numbers were allotted to new boilers earmarked for nine ERO’s already issued, with the new boilers not necessarily of the same type. But if so, then the intention was not strictly adhered to, as only 1422-27 were used according to plan. 1428-30 did not fit into any neat category:
1428 was possibly a Stirling replacement boiler (its barrel was 10′-0″ long, and not 10′-1″) taken from a withdrawn Sturrock engine, and now fitted to a Stirling engine, No. 844.
1429 was probably taken from a Stirling engine (its barrel was 10′-1″ long), and was now fitted to a Sturrock engine, No. 308A.
1430 appears to have been allocated to the 1898 boiler (again with a barrel 10′-0″ barrel) fitted to Sturrock engine No. 401, which became 401A when Ivatt’s first Class K1 0-8-0 was built (2/1901). This boiler latterly became Stationary Boiler SB239 at Langrick Pumping Station.

BO544 (28/1/1902). 10 domed boilers for new Class C1 (EO230). These had deep fireboxes, with a comment in the boiler order book: “These will not go into 401 class”. All subsequent boilers of this type had shallow fireboxes, making them suitable for Classes C1, K1 and L1. One of these boilers (1481) received a superheater (4/1909). Four of these boilers (1483/89/82/87) were subsequently fitted to Nos. 121 (4/1919), 141 (5/1919), 449 (4/1923), 411 (1/1924), from which it may be presumed they had been given new shallow firebox casings to make this possible.

These larger boilers were then marked for renewals for Class K1, but for which there was no immediate requirement. Later, 5 were taken for new Class K1 (EO247, issued 1/1906), leaving 5 for renewals. However, by the time the order was completed, they were once again suitable for Class L1.

The next duplicate number available being 1758, 5000 was simply added to it, and the main list boiler number sequence carried on from 6758 without hindrance to 9996 (reached in 1949).
