Hi CD

The plate seems to have originated from a lanc that was scrapped – most likely at the wars end. Maybe contacting the EAFM is the thing to do…!

Thanks for looking

There is a list of Mod Numbers in ‘The Lancaster Manual’ published by the RAFM (basically AP2062A & AP2026C) that goes from 397 to 805 (approved up to 31st January 1943) but none of the mods you listed are included.

There are gaps; for example 434 and 436 are there but nothing is listed for 435.

Sorry can’t help other than that; where did you get these mod numbers from?
