Back in 1954 I cut the solid petrol pipe off my 197 Ambassador because it kept breaking . I replaced it with a new invention then on the market, namely a piece of flexible rubber tube.
Although new to motorbiking, at the time, somehow, I knew, I just KNEW, I should keep that piece of old solid pipe.
How right I was ( the Hoarders instinct was with me even at that young age , you see it is INSTINCT, and is not learned ,nor discarded)
That bit of old pipe was EXACTLY what I needed to repair something else only a few days ago!. It is neither here nor there that it took me 3 days to find it, and my workshop had to be turned upside down, it was the right pipe at the right time. What more do you need to prove you should NEVER throw anything away. "It might come in handy ,dear"
