Justin,
My filing system could do with some refinement - while I found Hull # 1846, I can't yet find 1902. I'll let my brain recover from scrolling numbers and have another look later on. It is possible that 1902 is on one of the pages I didn't photograph.
Nonetheless, 1846 is attached below - doesn't provide much info apart from an ARN (which might possibly have doubled as a T number) and the original engine # .
