We have a very old Mauthe Grandfather clock that has dropped some of its chimes/rods during a move. We tried to reinsert but cannot loosen the screws in the chime block. It is a Westminster chime (photos attached). We are in search of a replacement Chime Block - would like one exactly as the one in the photo. It is 8 rods with longest being 21". Any help would be greatly appreciated - we have searched the internet but to no avail. Someone suggested replacing with a Hermle but not sure if that will work. Any thoughts?
