You should only need one slipper Andrew; that's what your machine would have been supplied with.
If there are chains each side, they might be a pair of check-chains to lock the front axle when manoeuvring the machine.
A length of tow chain may also have been present for off-set hauling when use of the draw bar would have been difficult (such as a narrow gateway).
Slippers do pop up on ebay from time to time.
