Its a little perplexing .In Canada the nose shown on end appears to be the full length article -by the time it appears in Dick Riachrdson’s garden the 40 inch extension piece seems to have been removed but subsequently that part has either been fabricated or refitted before fitment back onto ‘KB976’ at Brooklands.

The 40 inch extension would have been removed when the long nose from KB976 was fitted to the fuselage of KB994, during a period in the mid-1980s when RCAF 408 Squadron started to reconstruct KB994 as one of their own Lancasters in Canada. There are some pictures of the joined KB994 fuselage / KB976 nose on the website too.
