Or are they square to the strings with a short bore? We had a discussion about this a few months back. You might check the archives. Some of it ended up in the Journal Q & A Roundtable a few months ago as well. The Feurich 220 grand that I have (whose agraffes were recently mentioned) had a very short bore (I don't remember the numbers offhand, but it may have been more than 1/4 inch), but the hammers were angled back so that they were striking square to the strings. As far as I know this was the original setup. This is a high quality piano with a Renner action. The action regulated properly with things set up this way, so I have to believe it was deliberate. This generated a discussion about whether the 'proper' setup is to have the hammers square to the shanks. When I replaced the hammers I duplicated this setup. The piano plays and sounds fine.
