I had a very large collection of 32nd and 72nd scale. Mostly Airfix soldiers from all the major nations and quite a few vehicles, buildings, bridges etc.
I must have carefully boxed up thousands of pieces. The 72nd scale in tobacco tins, the 32nd scale in one and half gallon plastic tubs. I left them in my mother's loft and left the country for a few years.
I came back one year and found out she'd given the lot away!
