Cheers, Steve, WD16H C4104995 (the same contract as mine). I calculate it to be W3438 which seems to have survived the war after a rebuild (perhaps not surprisingly as it probably saw only Home service). It received the rebuild number C1436425 before becoming 73 YB 46 in the post-war register and finally being disposed of under MoS reference E/61/1/521 on 5/11/1957. Is it still out there ?
