When I was a callow teenager and living in the East End of London I had a bosom pal by the name of Dave Biber. In April 1943 I was shipped to North Africa, Dave, by then in the RAF, was posted to an airfield in Burma and we were not to meet up again for many years until Dave & his wife moved to Israel and we once again made contact. In his flat in Netanya, Dave had a pair of Japanese swords hung on the wall and also a framed certificate that gave him permission to have them. Dave always promised to tell me the story behind his ownership of these swords but, as often happens in these sort of scenarios, he never did and now, by his much lamented passing, he never will. Just another of life's un-solved mysteries.
