I have restored several of these Spanish street pianos as well as some
larger German and French full sized ones.  Here is the last small one
I did which needed new tuning pins because of the weather change and
the fact that in Europe they used 1/0 tuning pins.  Also there were
several other things that had gone wrong in this one as well.
