Hi Dieter

00002 is a coolant Avimo coupling spacer which goes between the thermostat and the radiator.

00004 looks like the engine starter motor, the AM ref isn`t a Merlin part number, so I am not 100% sure, someone else will be more familiar with the numbers I`m sure.

00005 and 00006 are the AMAL fuel pressure regulator which goes between the fuel pump and carburettor.
