Seems to me like if you have already started to work the Bridge off, the
disscussion about what you had or had not checked is a mute point. If
its not hide glue, then you might just fire off an email to Steinway
Hamburg and ask them what they used.

In anycase... the basic idea is to loosen the glues grip with both
wedges, the appropriate solvent in modest amounts, and perhaps a  small
amount of heat.

You might also double check the notching on the outside chance that
might be the source. I've run into a few instruments along the line that
either had too shallow a notch here and there, or not wide enough. Even
ran into a Petrof upright once that had a bunch of chunks of saw chips
stuck between the strings and bridge... But thats another story :)
