I don't recall encountering a 300 blow tip...
I have done much demolition with a #4 NG/Oxy tip. Never encountered anything it wouldn't cut, but lighting a large natural gas/oxy torch was more art than science...

I googled and couldn't find them. I am guessing the name 300 blow tip was maybe slang the guys used. I do remember the welding shop stocked them and the torches for a Pullman Standard train car repair shop we had locally.
