M45, LG45, LG6 sump.

This replacement sump has been designed to fit all the Meadows 4.5 engines that Lagonda used between 1933 and 1939.  There were numerous design changes to the major units of the engine through this period, and it may be that you will need to 'fit' this spare sump to your particular engine (which may itself have been modified over the last 80-90 years).  This could include an amount of machining and detail fitting.
