The boiler: test fitting
By January 2018 the boiler and firebox cladding had been completed and then dismantled. The boiler had passed an ultrasonic test on the thickness of the plates and passed a non-destructive test for cracks. Work had commenced on drilling out firebox steel stays and grinding off rivet heads holding the foundation ring before the boiler headed north.<ref>Howard A, 4150 Fund Facebook, 20 January 2018</ref><ref>[http://www.4150.org.uk/news/4150_jan18.html The 4150 Fund - Restoration update January 2018]</ref>
The boiler was moved from Bewdley to Bridgnorth on 18 June 2018. {{As of|2021}} it is for work to be carried out in the boiler shop where work is approaching completion. On 29 December 2022 it was temporarily lifted into the locomotive's frames to enable all the large copper pipes to be made up and fittings test-fitted. It will need to be removed again at a later date to carry out hydraulic and steam testing<ref>4150 Fund shareholder update, January 2023</ref>.
