I will assume you are just trying to make the piano work, rather than a thorough rebuilding job. The thunk may simply be 94 year old bass strings gone tubby. New strings should fix that. Remove bass strings, check bridge - if it is not loose from apron, or apron is not loose from board - I would suggest to just leave it alone. I have seen some screws in bridge tops to appeared to be original.
