You're right, National did make a few brands but none of them look close enough to the Brunswick. The ones that look similar are the Damascus and the Romley A but there are things that are different. I don't know if I mentioned this but on the base of the machine and under the largest slotted bolt, there is a bit of light paint (You can kinda see it in the picture). It's very crude but the Brunswick has designs in all those places that vaguely match the designs. I also picked up some rust removers today. I decided on krud kutter. I put some on, waited 20 or so minutes and then wiped it off. Underneath was black paint that was cracked and ugly but no lighter stuff so just by removing the rust, It's impossible to narrow it down to a specific brand. The Brunswick is the closest and that's what I'll go with.
