I am no expert on Ibach specifically, but I think some of your 
observations are actually standard features of this piano, and typical 
of many other German instruments.

Many German brands used brass bridge pins in the past.  Did this 
piano's pins look like brass? It is quite obvious to see.

Many German grands were designed with overstriking hammers.

Are you sure it was repaired? European pianos often have soundboard 
screws.

Ibach is a very old company (1794).  They made some interesting pianos 
in the past, for example they built double overstrung grands and 
uprights.  The bass bi-chords cross over the tenor strings as usual, 
but the mono-chords cross over the bi-chords, I suppose in an effort to 
accommodate longer string lengths.
