The Imperial 70

If you want to collect something that is relatively cheap to buy, then old typewriters might be an option, provided that you have the room to display them. This Imperial Typewriter Company machine dates from between 1962, when the model was introduced, to 1968, when it was superseded by the Imperial 80. They appear on eBay for around £10 to £20 plus postage (which is often as much as the typewriter itself), although this one was for sale in our local Oxfam shop for just £4.99, although I cannot say whether it was in working order.
