My tin can stilts were made out of blue and white striped jam tins - jam seems to have come in tins at one time . I had wooden stilts which we still have and our girls used them.
Favourites - washing machine I wrote about on another thread - Hoover with wringer on the top. You wind the handle at the back and it agitates the water. Still works now.
Dolls bungalow, roller skates like groom described, car garage with a lift to get the cars to the top floor, betta builda - bit like Lego only smaller, sindy doll and making things for her such as a wardrobe made out of a shoebox with string for a rail and matchboxes with those gold stud fold back clips for a handle to make drawer handles.
A ladybird book of things to do and make and making a toy that moves using a wooden cotton reel, cutting the edges to make it sort of serrated so it has some grip, then put a bit of candle on the end and an elastic band through the middle held on a used matchstick. You wind up the band with the matchstick then put it on the ground and watch it go - great fun. Best description I can manage. If I can find the book I'll post a pic. It's a good one for doing with bored kids but plastic cotton reels don't work as well imo.
