Five years ago the school I work at had aStwy D donated (then 25 years old) that had/has such a crack.  It doesn't seem to have gotten any worse, but the powers that be want to know what it's prospects are.  I know there is a fix available (unaffordable at present), but haven't a clue as to what to expect without making the repair.

Hi Alan,

I am going to assume that your question is sincere, despite the April 1 date.  If I am completely missing some humorous content, it certainly won't be the first time.  ; )

My response is just a question:  are you sure that the metal is cracked?  

It is not uncommon for the filler or japanning to crack on the surface of the plate, with the metal intact, as in the picture below.  When that happens it's usually a cosmetic defect, not a structural one.

If the plate is really cracked, you will be able to see the jagged crystalline or granular surface of the metal inside the crack (use a strong light and a magnifier if necessary).  Sorry, I don't have any wisdom to offer if it is indeed cracked.
