Interesting

Notice the overhead belt drive for all the machinery.

That's how the industrial revolution was powered.

We have a small engineering company in our local village - I was hunting around the back of some of the buildings and came across one of the original buildings from the 1600's.

I was talking with the owner who was explaining that the site and buildings was the original 300+ year old blacksmiths forge.
There was a big steel shaft going thu the roof one one building, out and thru the next building.
In one building was the original forge and a 'power hammer' that was driven by a belt driven from a pully-wheel on this shaft.

It is interesting to see 100s of years old technology - not in use but still installed and which could be made to work.
