Factory Overstrike

Hi Phil

No, at least not to this degree.  Besides... the  key word is <<clue>>.  
Think about it.  A typical hammer shank is 5.5 mm Ø. This then again is 
regulated to 3 + mm above rest rail cushion.  The thickness of the 
cushion on the rest rail is what... 6 mm ?? (guessing).  Thats about  48 
- 11.75 mm blow distance.  36.25 mm
???  That means hammers would have to have worn down somewhere around 8 
mm.... which would dig into wood on most hammers.

Then of course there was the bore length to the core tip on hammers I 
removed.  You'da had to have monster amounts of felt covering these to 
end up with an origional bore length of 53 (which was what was needed here)

Of course tho... worn hammers require a higher drop screw, and letoff 
setting, and rest rail setting.

Wouldn't you expect to see both of these things with severely worn hammers?
