I met with Gregor today and spent some time looking over Old Nail. The instruments are:

Top left 'AC' (delco) Water Temp 40 to 120 deg C

Bottom left 'AC' Oil Temp 40 to 140 deg C

Centre 'Smiths' Chronometric Rev Counter 1 to 10 (x1000) Rpm - Redline 7800

Top Right 'AC' Amp Meter -45 to +45

Bottom Right 'AC' Oil Pressure 0 to 100 Lbs/sq'

I hope this helps.
