The smell of something I think is called Teak Oil. Mum used it to polish our coffee table. That coffee table was our dining table sometimes, my Dad caught his shin on it countless times, and there are toothmarks round the edge from when my sister and I were teething. It was one of the very few (possibly the only) pieces of furniture that moved back to England with us from Belfast.
It's in Mum's garage now, and I've said I want it, once I have anywhere to put it.
Also, the old style Nee-naa sirens on emergency vehicles, when heard without accompanying modern woo woo style. Growing up where I did, we heard a lot of them.
