early 240 B21E ignition control unit
 

Hello ,
Has anyone got a spare Bosch ignition control unit for a 240 1975 to 81 ish , only used on the B21E B23E engine .. It is a square black BOSCH box with some alloy cooling / mounting fins mounted on the winscreeen washer bottle and has a plastic protection cover which slides over it .... 1266714

Thanks in advance Nick
