Lovely job Ian.
So sorry I missed this question first time round Alan, as far as I remembered it was aged brass coloured. There was no guard on it at all, something to give me nightmares these days but thought nothing of it as a 8/9 year old wandering round the running engine. It was a 3VSH but the hand start had been moved to the same end as the flywheel so the gear box could be fitted to the other end, this video suggests my memory was wrong and it was polished steel however.
Same engine but ours had the fuel tank on the engine room wall and the rad was replaced with raw water cooling. Lovely sound.
