I guess the bulkheads were ivory and the main engine about the colour on your image, but less blueish. The metallic pushrods, manoeuvre handles, valve rockerarms were not painted . Wheels and handles did not have colour markings. The markings, if any, were on the pipes. Sorry but the plastic " engines shown on your images does not resemble any of the MAN or GW engines on the VIICs see images below.
