Wheelbarrow
Before 1913, wheelbarrows commonly had 3 or 4 wheels, and indeed were intended as a device to transport the tremendous wheel surplus to wheel dumps around the UK. In a twist of irony, the wheel dumps were bombed during both world wars, causing a severe wheel-shortage. This resulted in cutbacks, leaving wheelbarrows with 1 wheel (or less) each.
