Just to correct a few bits on the history, which looks like it is taken from the book by William Coles-Finch, which is sadly riddled with errors. I'm slowly correcting it in five volumes. Coles-Finch lived in Medway all his life, and missed mills which he might have known as a young man.
The windmill was built in 1802, by a chap named John Peak. The first lessee was a lady named Elizabeth Medhurst. The Wakeley Brothers took the mill in the 1850s, and raised it then, rather than in 1902-3. They worked it until the 1890s, when they gave up probably due to the advent of steam. So it had a continuous working life of 90+ years.
It's interesting that they still renewed the insurance premiums every year up to 1910, which could suggest foul play, as with many other windmill fires around this era!
There was also an early windpump on Upchurch marshes, recorded in a sale notice of 1810.Upchurch windmill in 1903 on Windmill Hill, Upchurch. A working mill from 1819-1843 + 1858-1872 + 1903-1910. Owned by William Wakeley who raised the whole structure on a brick base in 1902/1903 to get better wind-power. Fire completely destroyed the mill in September 1910 and it was never rebuilt.
The general view of the windmill burning. A local photographer had taken the scene a few years earlier. He added a few dark marks for smoke and put the postcard out for sale again!
