This hot air engine is the smallest engine Louis Heinrichi made. It was used in Victorian households for a fountain water pump and other domestic applications, as well as the purpose that this particular hot air was used for. My friend purchased this engine from a local dentist about 30 years ago. The dentist was long retired and used it to run his dental drill at the beginning of his career. Upon his passing, my friend's widow said that he would like it if I had it now to display at local shows. It runs great with only a small alcohol burner. Through research, I found out that it is from the third quarter of the 19th century (about 1885). thanks for looking....... hotairfan.
