The Hoffman company is still in business as Hoffman Video Systems in LA. They did make it as far east as Texas as I have several of their B&W sets. I heard that they had a plant in St. Louis MO. at one time.
I use a 25 watt iron on PC boards. This seems to work well does not damage the board. The only time I have had to use a soldier gun near the boards is to disconnect soldiered chassis ground connections as used in the Philco Seventeener, etc.
