Still see some folks outside the US referring to their weight in "stone",... why???
What's that gold saran wrap thing they keep using for lunar mission? Always looked weird to me.
It's gold foil used to reflect IR radiation.
Why not gild the whole vessel? It looks like a Tabac puck with that foil loosely wrapped.

My dad and i bought a series 3 Land over a few years ago and spent a happy couple of years restoring it. The thing had metric, imperial AND whitworth fastenings. Oh how we enjoyed the constant ordering of new spanners...
...Determined to achieve high standards of accuracy he constructed a measuring machine, based on Henry Maudslay's measuring machine accurate to 0.0001" and another which could detect differences of less than one millionth of an inch. The standard method of measurement at that time was by using callipers and a graduated rule. Engineers were accustomed to working in 'bare' of 'full' measures until the late 1830's. An article published in the Manchester City News in 1865 commented that "Mr Whitworths foot rule, on which he had the thirty-second parts of an inch marked, was regarded as a curiosity, and many did not hesitate to affirm that to work to such a standard was an unnecessary refinement". He was one of the first to point out the advantages of decimalisation, the common fractional system was impossible for precision work...
Just a light jacket.
There's been talk of changing since the '70's, it just didn't happen. It is slowly changing on it's own because of imports and exports, and it is taught in schools.
What about the clock? It should be based on 10 also.
