Second Generation Steamer i.e. Child

Hi Folks,
It's been awhile, my youngest son and wife just bought their first home. Steam heat, I believe a Columbia boiler, not sure will get some pictures. We are swapping out the old main vents, for some faster venting. After this we will assess the radiator vents and see how these are working. I assume they are over 10 years old. So once I get some pictures of this system, I will start picking your brains for advice. I also have passed on my books from Dan, and trying to get them educated on steam heat. So it's nice to back in "The Wall" for the kids.
Thanks for all the help you gave me.
