Please forgive a slightly sideways diversion on the subject of sparks.
Quite the opposite of putting the spark down as deep as possible into the combustion chamber, the snaps show a way of raising it. The example came from a large six cylinder Crossley years ago, whose then owner had not got round to dealing with sloppy rings and therefore much oil coming up round the pistons. His answer was to put on what I've called barrels, to raise the plug above the swirling oil and get a clean spark. Long since removed by the current proud owner, but we are having challenges finding out what they were officially called and how long ago they were offered for sale. Round the barrel reads "AC type B Made in England"
No matter how arcane the subject, this forum will always produce an answer, well always has done so far. The white background has nothing to do with table napkins in the café where this vital historical matters were discussed this morning, good lord no.
