Mine is a yellow duck that shows the temperature of bathwater.
It was in an envelope, sent by the local council, concerning safety in the house, a few years ago.
Checking the water temperature for the children's bath it has been invaluable for me,
though I still double check with the elbow.
Simple but very useful.
Well they were free but more of an inheritance really. My dad was a bricklayer all his life and when he died in 1976 I got his trowels, spirit level, plumb lines, snap string and hod along with his plasterers floats. They have travelled with me and been used all over the world on the half dozen or so homes and gardens we have owned. Google Earth still shows the brick patio and walls I built with those tools in Hurst, Texas when we lived over there. Definitely my best and most used freebie.
You've just reminded me of the 'dollies' my dad made for me many years ago when I was a boat builder. Lathed to the right weight and used many times repairing clinker built boats.
Haven't used them for years but still in my tool box.
