Those are just old scrapbook copies (which, BTW, make the same provision 
for anchor bolts as the newest revs.) I ought to get gigged for referring 
to an old spec, God knows I've waved my arms enough about using current 

Point taken on the anchor bolt provision. I noticed that Grade B is 
suggested for cast iron flanges, but steel where the only chemistry 
control is phosphorus and sulfur does seem like a holdover from riveted 
iron boilers.
