which would explain why 506 was offbeat

These photos show #30506 undergoing steam tests and setting of safety valves.  One flue tube was weeping slightly at the firebox end and this will be remedied when the firebox has cooled enough.

Bubs grinds a final finish on a gland packing (7 May '98).

The specified material is a closely-guarded MHR secret, but we discovered it lasts very well  (and doesn't wear out piston rods) by a series of tests on the A4: "Sir Nigel Gresley".

   

The boiler had passed its annual inpection by the insurers, all the motion had been refitted and the engine was ready for service by mid-day on 21st May 1998.
