Delighted to find that we are related, if a long way away, to R R Angerstein. My father, Torsten Esselius Berg's great work in retirement was to make an English translation of RA's notes on his trip to England, but, alas, when he died in 1978 the translation was incomplete. After I retired I was able to take up the work again, with the help of many experts in industrial history. It was published by the Science Museum in 2011 as 'R R Angerstein's Illustrated Travel Diary 1753-1755' and with over 400 sketches and diagrams gives a unique and much valued view of industry in Britain in the middle of the 18th century.
