MG MGA - Lightning jack

For those that are interested, I have just come across this jack, but I don't know anything about it. One for Steve Gyles I think.

It looks a bit agricultural; it would be fascinating to know its history.

Maybe the idea is that you raise it to its maximum height during a storm and it protects you from getting struck by "Lightning" LOL

I often had to change the wheels and brakes on my Lightning fighter but I don't remember using this type of jack. And no, I am not kidding. As Lightning pilots we had to be certified to carry out turn rounds on our jets in the event we landed at 'non-Lightning' capable bases.

Tyres lasted 1 landing in crosswinds above 20kts. (tyre pressures were something in the order of 300psi I believe). If the brake-chute failed it was a double tyre and and brake unit change. Even on standard landings the brakes glowed white hot - we landed at 155kts (178mph).

So both the groundcrew and the aircrew became quite adept at jacking up the u/c and changing wheels and brakes.

I wonder what country the patent number applies to. A 5-digit number would be very old in many countries. UK numbers were (re)started at 100,000 in 1916. http://www.ipo.gov.uk/types/patent/p-about/p-whatis/p-oldnumbers/p-oldnumbers-1916.htm

You call that a jack... this is jack! (to quote Crocodile Dundee)

If the jack is, indeed something for agriculture implements, here is a gentleman who would know something about it. Paul Bowyer had a whole yard full of yard full of farm implements since he did contract work for farmers in Wiltshire. His e-mail is kaympaul@tiscali.co.uk or paulandkaybowyer@hotmail.co.uk
He also is into restoring old lorrys. Cheers - Dave

While it may of course have been for farm use, the word 'agricultural' in the sense I used it above is often used over here to describe something that is very basic in design, functional and probably reasonably efficient. Do you use the word in the same way your side of the pond?

I reckon the Lighning Jack maybe of Australian origin made by Lightburn Industries - they were an engineering company that made jacks for many Holden (GM) cars in Australia back in the 60s and 70s and use the name Lightning for some of their products including small concrete mixers. They even made small car!
