St. Louis: Heine Safety Boiler Co., [1919?].
Original Wrappers. With a frontispiece of Plant No. 1 in St. Louis, and a splendid folded color plate of a Heine Boiler as set with Stoker of the Forced Draft Underfeed type. A nice copy. We locate only a couple of copies on OCLC. There is a bit of wear to the bottom of the spine.
Very Good binding.
