For me it was a passion for Dinky aeroplanes. I went to jumble sales with my pocket money and ended up with 30 or 40 of them. I remember the Ensign (two off), the Ju-90 (two off), the Singapore, the Mercury/Maia combination, Amiot 360, Battle, DC-3 etc etc.
My mates and I also discovered a fantastic junk shop that had the old black recognition models left over from the war. They were made of bakelite or wood and I had quite a few including the C-46 Commando and the B-26 Invader. I also remember having a Japanese Betty, Helen and Mavis flying boat.
