Here is the info i got from them:
"We shall need to carry out a detailed examination and assuming we find the cartridge repairable, our charges to carry out a complete overhaul to include materials as necessary and auditioning will be between £291.00 - £330.00. With the work carried out we aim to return the cartridge to as near new condition as possible. Should we find the cartridge in relatively good order, apart from a badly damaged cantilever or the stylus to be showing excessive wear, our chatges will vary between £120.00 - £180.00."
I use my AT-ML180 and AT-ML170 on Victor UA-7045, Lustre GST-801 and Reed 3P "12 Cocobolo.
