You've bought the wrong hammers, which are most likely to be too 
heavy even if you find a way of planing them down to 10.5 or 11 mm 
wide.  This would mean you'd end up with too heavy an action or too 
sluggish an action owing to the lead you add to compensate for the 
over-heavy hammers.  Can't you send them back and get the proper 
lighter hammers for the early models?
