In 1858 Philo D. Beckwith in Dowagiac, Mi. built a foundry when he commenced the manufacture of the Roller Grain Drill. In 1868 Philo D. started the Round Oak factory. He continued to manufacture the roller grain drill for many years along with his stoves and furnaces.

Catherice Scott ca 1844 two daughters, Della and Kittie In 1878 Kittie and her husband Fred Elmer Lee joined with other heirs in erecting the handsome opera house to the memory of P. D. Beckwith.I do not know the year that it was torn down.The park is named after P.D. also. I do not have any information on it. The Round oak factory exsited for many years after Philo died. My Husbands father worked there untill 1939. Do not know the year, but it closed shorthly after 1939. Sorry, I can't say what the value of a stove would be or how many are still in existance. I have seen several stoves in Az. Also, I don't have any info on anything of his estate. I do have several articales from the Dowagiac Newspaper that was writen about Philo, family and the Round Oak factory.Also a picture of him and the roller grain drill. If you would be interested on anything I have, I could make copies and send to you.
