I can't remember the first, of many, model aircraft I made but the one I do recall is that which my Dad made for me during the war. I think it was in 'Spitfire Week', raising funds to buy aircraft - nominally Spits. The plans could be bought, possibly 6d?, and there was a prize for the best model. Ours (I took possession of it) was a beautifully hand carved solid-wood one, painted IIRC, and I was sure it would win. Of course, it didn't, but it kept me happy for many years thereafter.
