R-R PIII - core plug tool Below are two views of the core plug extractor that I had to make.   The left hand shot shows the pins slightly off perpendicular because the 'A' side plug proved a little stubborn.  On the right is the tool attached to one of the plugs.  A square nut was cut to fit a 9/16" Whitworth spanner to give a good purchase in case I met any resistance.

R-R PIII - x-shaft core plugs The plugs are stamped with the engine number and engine side although they are both right hand thread.  Sealing is the usual aluminium washer.
R-R PIII - cross-shaft gear

One of the cross-shaft gears used to drive a distributor.  There is no obvious method of extracting either the gears or the shaft.  Given the plethora of special tools used everywhere else on the engine I can only imagine that the designer was having an 'off' day.
