Yep! The question you have to ask yourself is: if you bought a steel bicycle
today would it be manufactured in the same manner as an early 1900's bicycle?
The answer, of course, is 'No'. I'm currently restoring a 1970's steel Schwinn cruiser. The tubes are
literally 5-10X thicker on that bike than a modern steel bike. There's a
lot of steel there! And it doesn't hurt that the manufacturing tolerances are such that it's virtually impossible for the frame to trap moisture. Still, there's quite a bit of rust on the inside of all the tubes; at least the ones that I can easily examine. Does it worry me? Not given the thickness of the tubes. But if the tubes were as thin as they are on modern steel bikes? I'd be a
lot more worried about rust, proper frame prep & maintenance, etc.
