There are shall we say six general types of spanners, Face, Hook or Pin, and each can usually be found as either Fixed or Adjustable. You need a Hook Spanner (probably made by either Armstong or Williams) to fit the diameter of the coupling nut that retains the chuck. It can be either fixed or adjustable. The coupling or retaining nut stays on the spindle, has RH threads, and is turned CW (looking from the tailstock end of the lathe) to loosen. You should have no problem finding one on eBay, once you measure the diameter of the nut.
