Ian,cant help you with SMB emc, but i did pits for a friend in the 80's I remember the commentary was a t the bungalow . G Cannell I think ? .

The EMC came into refuel Brian Reid ? those days they were allowed their own dump fillers ! Geoff had reported that the emc was misfiring , we were the next pit to the EMC team when Brian pulled in they pulled the fairing, missed the fuel tank , and covered me with avgas ! it was a blazing hot day and Jochen who pitted for Helmut Dahne and Hans Otto helped me out that day . Thanks for bringing up EMC great memories for me .
