In this month's Miscellany, Machiel Kalf posed a question about K.L.G. spark plugs. I did a bit of digging and the story is amazing.

You can read it in the Motor Sport archive here..........

When I was a metallurgist in our Steelworks we used to make steel specifically for sparkplug bodies. It was a low carbon resulpherised steel for ease of mass production with easy machining ( hence low C andhiger S). Not always an easy steel to make but we had the expertise and experience. Usually 70 tonne batches but up to 150tonne in the newer furnaces. Usually sent to London Works mill in the Midlands where we had a mill to roll it into hex bar.
At one time we lao sent similar types of steel to Italy via a ship from Briton Ferry near Port Talbot. The Italian company rolled the ingots into nd user steel configurations.

Fascinating stuff indeed, 5 bob each, a full set for a quid! And I seem to remember they were still the same price in the 60s. No mention of NGK, of course when the article was written in 1952. On holiday in France some 30 years ago, browsing in an antique shop I came across a KLG tin which would have contained a dozen or so spark plugs, I bought it and still use it to keep bulbs and other bits and pieces in the Morgan's tool box

My Grandfather had a British motorbike with one cylinder in the fifties, which he kept in the shed. As a young boy, I spent time down the garden watching him struggle to start this bike. When he died unexpectedly aged 60, the first thing my Grandmother sold was the motorbike, so I have no idea what it was.

Years later when I cleared the shed out, I found a large selection of spark plugs. None were the same. There were certainly K.L.G. and Lodge amongst them.

I think I inherited his mechanical curiosity because no one else in the family shows any mechanical interest or ability.
