Judging by the standard of Meteors we had at Oakington the instrument fit, when they came out of major servicing, depended on what was handy at the time.
Their final years at Changi necessitated a mod program. This involved drilling the aileron hinges, threading them and inserting grease nipples. This was because at manufacture they had been 'greased for life', at that time about 4years/1000hrs.
