@Setanta,
That is fascinating, Set. We have a saying here about "not being worth a brass farthing" and now I know where it probably comes from.
Birmingham has always had a great reputation for light engineering, and still has many small firms dotted around the place, churning out all manner of metal nuts, bolts and fittings.
During WW2 it was the main manufacturing centre for aircraft, and, as you can see by this monument, they are proud that they built many a Spit and Hurricane there.....
That monument is on an area known as Fort Dunlop, which the Luftwaffe did their very best to flatten during the war, but the ingenuity of the Brummie was such that they were able to carry on building them throughout, and were even receiving wreckage from around the country so that they could salvage and re-use any bits that weren't beyond repair.
Even today, Birmingham churns out the majority of Jaguar vehicles that are exported around the world, their workforce recently being almost doubled because of the increase in demand for the various Range Rover models.
Vast fortunes were made in Birmingham when the industrial revolution kicked in, sometimes on the back of the most unlikely ideas and items. Lightbulb moments were happening on a regular basis, many of them resulting in massive trade, profit and employment.
Take the humble pen nib.
During the 1850's, it was reckoned that if you were to do a survey of pen nibs in any large office in any part of the world, half of them would have come from Birmingham.
Rather than copy pasting, I'll just paste the link...

Very early on (mid 1700's?) the reputation for precision work in Birmingham was such that Goldsmiths and Silversmiths had been producing high quality items for years, and pretty soon afterwards Birmingham was deemed important enough to have an Assay mark of its own, a high honour indeed.
It is said that the Government Assay Official met with dignitaries from both Birmingham and Sheffield one evening, to discuss which symbol should be "awarded" to each city.
They met in a pub called The Crown and Anchor, where it was decided that Sheffield should have a Crown mark, and Birmingham the Anchor.
Strange, considering that Birmingham is totally landlocked and about as far away from the sea as you can get in the UK.
So, if you see a piece of silver or gold with the Anchor, you know where it was assayed.
Off to walk the hound now. Please excuse typos, as I was doing all this in a bit of a hurry.
Back later.
